autotournament.gg

The Auto Tournament homepage. Next.js (app router), React, TypeScript and MUI.

Sponsor Auto Tournament

Running tournaments or LANs with Auto Tournament? Your organisation can keep it growing. Auto Tournament is built and maintained by one person — sponsorships pay for development, test servers and infrastructure.

Using it for a business, paid events or hosting? That needs a commercial licence → Licensing

src/theme/tokens.ts and src/theme/theme.ts are the Auto Tournament design system: colours, type, radii and motion. The app will move onto the same theme.

yarn install
yarn dev        # http://localhost:4611
yarn build

drafts/ holds the static HTML design drafts the site was built from.

Deploy

Runs as a Docker container on the docs host. A cron job runs scripts/auto_update.sh every five minutes and rebuilds when main has a new commit. The container listens on port 31236, and the astro Cloudflare tunnel routes autotournament.gg to http://dev.lan:31236.

Payments

The price calculator's "Buy with card" button starts a Stripe Checkout Session through POST /api/checkout. Set these in a .env file next to docker-compose.yml on the server (git- and docker-ignored, read at runtime; env_file with required: false needs Docker Compose 2.24 or newer):

• STRIPE_SECRET_KEY: a Stripe restricted key with Checkout Sessions write, Prices read and Products read (optionally Invoices read, see License keys, Customer portal write, see Console, and Refunds write, see Refunds). Unset means card checkout is off: the route answers 503 and the calculator offers the email request instead.
• SITE_URL: base URL for Stripe's return links. Defaults to https://autotournament.gg.

After editing .env, run docker compose up -d to restart the container with the new values.

Checkout asks the buyer to accept the Commercial License Terms and Terms of Sale (consent_collection.terms_of_service). Stripe needs a Terms of service URL in Dashboard → Settings → Public details first (https://autotournament.gg/terms); without it, creating a Checkout Session fails and the calculator falls back to the email request.

yarn test runs the checkout, Stripe price, license key, license email, console (on an in-memory Postgres, PGlite) and CS2 compatibility tests.

Prices live in Stripe

Stripe is the single source of truth for the pack prices and server limits. There is one Product per pack (Servers S … Platform L) and three one-time EUR Prices on each, found by lookup key <pack>_<period>, for example servers_l_event, servers_l_year, servers_l_founder. The pack's server limit is the Product's max_servers metadata.

The pricing page, the terms page and /api/checkout read them through src/lib/stripePrices.ts (cached for 5 minutes) and check them before use: all 18 prices present and active, EUR, one-time, tax exclusive, and server limits that grow S < M < L. If Stripe can't be read, or the list fails the check, the site keeps the last good prices; with none yet (for example right after a restart), it shows FALLBACK_PACKS from src/components/pricing.ts and card checkout answers 503, so nobody pays a price that didn't come from Stripe. Look for [prices] in the container log to see why.

scripts/stripe-seed-packs.mjs creates and updates the products and prices. It needs its own restricted key (not the website's), with Products: Write and Prices: Write and nothing else. Create it in the Stripe Dashboard → Developers → API keys → Create restricted key. Run the script from this folder on your Mac after yarn install. The key is typed at a hidden prompt, so it never lands in your shell history.

Dry run first. It prints what would change and changes nothing:

cd ~/dev/autotournament/website && (printf 'Stripe admin key: '; read -rs STRIPE_ADMIN_KEY; echo; STRIPE_ADMIN_KEY="$STRIPE_ADMIN_KEY" node scripts/stripe-seed-packs.mjs --dry-run)

Then the same command without --dry-run to apply it. Add --archive-v1 to also archive the four old per-seat v1 products ("Servers license: per event", "Servers license: yearly", "Platform license: per event", "Platform license: yearly"). Running it again changes nothing when Stripe already matches.

Changing prices

Preferred: edit the PACKS table at the top of scripts/stripe-seed-packs.mjs (and FALLBACK_PACKS in src/components/pricing.ts to match), commit, then run the script (dry run first). A new amount creates a new price, moves the lookup key to it and deactivates the old one, so the old price stays in Stripe as history. A new server limit updates the product's name and max_servers. The site picks it up within 5 minutes; no deploy needed.

In the Dashboard instead: Product catalog → the pack's product → Add another price. One-off, EUR, the new amount, tax behavior exclusive ("Include tax in price: No"). Under the advanced options, set the lookup key (for example servers_l_event) and transfer it from the old price. Then archive the old price. Update the PACKS table to the same amount afterwards, or the next script run puts the table's amount back.

License keys

Every paid card checkout gets an Ed25519-signed license key. Ready Up and the platform check it offline with an embedded public key. Nothing ever blocks: a problem is a warning in the product, never a lockout.

Flow

1. POST /api/checkout puts the pack, period and max_servers in the session metadata.
2. Stripe calls POST /api/stripe/webhook (checkout.session.completed, checkout.session.async_payment_succeeded). The route checks the Stripe signature, then issues one key per Checkout Session (src/lib/license).
3. /pricing/thanks?session_id=cs_… shows the key. If the webhook hasn't arrived yet, the page asks Stripe whether the session is paid and issues the key itself (same one-per-session store, so never two keys).
4. The key is emailed to the address paid with, once (see "License email" below; off until Postmark is set up).
5. Every license bought with an email shows up when that email signs in at the console (console.autotournament.gg). That is the one place to see a license or its key again; the site itself no longer has a "get it again" page.

Issued keys live in Postgres (the licenses table, see Console), with a SHA-256 of the buyer's email instead of the email. Until the console they lived in licenses.json in LICENSE_DATA_DIR (default ./data/licenses, /app/data/licenses on the compat-data volume). At every start the site imports the licenses from that file that aren't in the database yet (log: [license] licenses.json import { inFile, imported }) and never changes the file, so it stays as a backup of the keys issued before the move.

Setup (once)

1. On your own machine: node scripts/license-keygen.mjs. It prints the private key and the public key; nothing is written to disk.
2. In .env next to docker-compose.yml on the server:
   • LICENSE_SIGNING_KEY: the private key it printed (base64 PKCS#8). Also keep it in your password manager. Never commit it.
   • STRIPE_WEBHOOK_SECRET: the endpoint's signing secret (whsec_…) from step 4. Unset, the webhook answers 404.
   • optional LICENSE_DATA_DIR.
3. Add the printed {"<kid>": {…}} entry under keys in src/lib/license/public-keys.json and commit it (public keys are not secret). Give the same kid and x to Ready Up and the platform.
4. Stripe Dashboard → Developers → Webhooks → Add endpoint: https://autotournament.gg/api/stripe/webhook, events checkout.session.completed and checkout.session.async_payment_succeeded (issuing), plus charge.refunded, refund.updated and refund.failed (refunds, see the admin CRM's Refund below). Copy its signing secret into STRIPE_WEBHOOK_SECRET.
5. Optional: give the site's restricted Stripe key Invoices: Read, so the invoice number is available too. Without it, only the order reference shows up.
6. docker compose up -d.

Without LICENSE_SIGNING_KEY, no keys are issued: the webhook answers 503 so Stripe retries for up to 3 days, and the thanks page shows the old "we'll email your confirmation" text. Look for [license] in the container log.

License email

When a key is issued (webhook or thanks page), the site emails it to the Checkout Session's email through Postmark's HTTP API: the key, pack, period, what it covers, order reference and invoice number, and the seller footer. Replies go to sivert@autotournament.gg. Open and click tracking are off.

Exactly once per license: the send is claimed in the database and emailed_at is written to the license's row when it works. A failed send never fails the webhook or the key; it logs [license] email failed with the license id and the error (never the address) and keeps it in email_error. It is tried again when Stripe delivers the event again (Stripe Dashboard → Webhooks → the event → Resend), or from the console's admin resend action.

Env, in .env on the server (all optional; unset POSTMARK_SERVER_TOKEN means no email is sent and the site works as before):

• POSTMARK_SERVER_TOKEN: the Server API token (Postmark → the server → API Tokens). Secret.
• EMAIL_FROM: default Auto Tournament <licenses@autotournament.gg>.
• POSTMARK_MESSAGE_STREAM: default outbound (the transactional stream).

Postmark setup (once), in this order:

1. Postmark → Sender Signatures → Add Domain: autotournament.gg.
2. Postmark shows a DKIM TXT record and a Return-Path CNAME (for example pm-bounces). Add both in Cloudflare → autotournament.gg → DNS, as shown there, with the proxy off (DNS only). Keep the Email Routing MX and SPF records as they are: Postmark doesn't need the root SPF, the Return-Path covers it.
3. Wait for Postmark to verify both, then send a test from Postmark to yourself.
4. A new Postmark account can only send to its own domain until Postmark approves it: request approval in the account if it isn't yet.
5. Put the token in .env and docker compose up -d.
6. Optional: a DMARC record (_dmarc TXT) once DKIM passes.

Public license check (/verify)

/verify/<license id> shows the licensee, pack and server limit, kind, period, updates until, and a status: valid, upcoming, expired, test, or not found (the same for every unknown id). Never the key, email, customer id or order reference. 30 checks per IP per minute, not indexed. /verify itself has the "Check a license" form (also linked from the nav); the thanks page and the console show each license's check link. Always on.

Rotating: run the keygen again, add the new public key to public-keys.json (keep the old one, so old keys still verify), ship the new public key in the products, then swap LICENSE_SIGNING_KEY.

Token format (v1)

ATL1.<payload>.<signature>

• payload: base64url (no padding) of the UTF-8 JSON below.
• signature: base64url (no padding) of the 64-byte Ed25519 signature over the ASCII bytes of ATL1.<payload>.
• The payload's kid picks the public key. kid is the first 16 base64url characters of SHA-256 of the raw 32-byte public key.

{
  "v": 1,
  "kid": "LsbOKx91J9fIxM0s",
  "id": "L-3kq8Zx0bQ1aR",
  "customer": "cus_…",
  "licensee": "Example LAN AS",
  "product": "servers",
  "pack": "M",
  "max_servers": 15,
  "kind": "event",
  "issued_at": "2026-09-28T10:11:12Z",
  "updates_until": "2026-10-05",
  "valid_from": "2026-10-03",
  "valid_to": "2026-10-05"
}

• customer: Stripe customer id, or the email when Stripe has none. licensee (the business name) is optional.
• product: servers | platform; pack: S | M | L; kind: event | year | founder.
• Coverage is by version line. Each release carries line_date, the release date of its major.minor.0. A release is covered when line_date <= updates_until (dates are YYYY-MM-DD, inclusive), so later patches of a covered line stay covered.
  • event: valid_from..valid_to is the event window (the dates from the checkout form, at most 5 days; 5 days from the purchase if they can't be read). updates_until = valid_to.
  • year: updates_until = purchase + 12 months. No valid_*: commercial use of covered lines goes on after that.
  • founder: updates_until = 9999-12-31.
• Ignore unknown fields. Treat any other v as "needs a newer release".

GET /api/license/public-keys returns { "alg": "Ed25519", "format": "ATL1", "keys": { "<kid>": { "kty": "OKP", "crv": "Ed25519", "x": "<base64url>" } } }.

Reference verifier

scripts/license-verify.mjs is the logic the products port. Offline; it uses src/lib/license/public-keys.json unless given --keys:

node scripts/license-verify.mjs <token> [--line-date YYYY-MM-DD] [--servers N] [--product servers|platform] [--now YYYY-MM-DD] [--keys file.json]

It returns { valid, status: "ok" | "warning" | "invalid", warnings: [{ code, message }], license } and never "blocked". Warning codes: updates_expired (line date after updates_until), too_many_servers, period_ended / period_not_started (event window), wrong_product (a Servers key in the platform). Invalid codes: malformed, unknown_kid, bad_signature, unsupported_version. Tests: src/lib/license/license.test.ts (throwaway keys made at runtime).

VAT threshold alerts

Sivert's ENK must register for Norwegian VAT (Merverdiavgiftsregisteret) once rolling 12-month license revenue passes NOK 50,000. src/lib/vat/threshold.ts sums every live-mode paid license's amount_total (on the licenses row: card sales in EUR, manual ones in EUR or NOK, see src/lib/license/sales.ts) from the trailing 365 days, leaving out licenses marked refunded, converts it to NOK with Norges Bank's daily EUR/NOK rate (src/lib/vat/rate.ts, no key needed, cached 12h; a conservative 12.0 fallback if Norges Bank can't be reached), and emails the seller (seller.email, src/components/seller.ts) through Postmark the first time the rolling total crosses 70%, 90% and 100% of the threshold. The email lists the rolling total (NOK and EUR), the rate used, every sale in the window, and the next step (register via Altinn, then update the "No VAT added" text and Stripe tax settings). Each threshold is tracked in the vat_alerts table and fires again if the total later drops back below it (old sales leaving the window) and re-crosses.

The check runs after every issued live-mode paid license (the webhook and the thanks page both go through issueForSession) and once a day at server start (src/lib/db/startup.ts). It never blocks or fails license issuing or startup: a failure is only logged.

Env, in .env (both optional):

• VAT_THRESHOLD_NOK: default 50000.
• VAT_ALERTS: default on; set to off to disable the check entirely.

Without POSTMARK_SERVER_TOKEN, a crossed threshold is only logged (the percentage, never an amount or the email).

All sales are converted with the latest rate rather than each sale's own day's rate — the rate moves little day to day, and per-day conversion would need one Norges Bank request per unique day. The rate used is always shown in the alert email. A license marked refunded in the admin CRM leaves the total; a revoked one (money kept) stays in it.

Tests: src/lib/vat/threshold.test.ts, src/lib/vat/rate.test.ts, src/lib/vat/email.test.ts.

Console (console.autotournament.gg)

The customer area: sign in, organizations with members, their licenses and keys, and invoices; and, for Auto Tournament staff, the admin CRM at /admin (below). Same app and container as the site: src/proxy.ts maps the host console.autotournament.gg onto the routes in src/app/console (/licenses is src/app/console/(org)/licenses), and the main site's /account redirects there. When AUTH_URL is a localhost URL (development), the console is at /console on the same host instead.

• Sign-in (Auth.js / next-auth v5, src/lib/console/auth.ts): an emailed link (Postmark, single use, 15 minutes; the link opens a page with a button, so mail scanners don't use it up, and carries only the token, not the address) or Google. No passwords. Database sessions for 30 days, stored as a SHA-256 of the cookie. Cookies are host-only (__Host- session cookie), so they belong to the console's host alone. Google accounts are accepted only when Google says the email is verified, and are then linked to an existing user with that email. Without POSTMARK_SERVER_TOKEN, email links are off in production; in development (yarn dev) the link is printed to the log.
• Organizations: name, org number, VAT ID, country, billing address. Roles owner, admin and member. Members see the licenses; owners and admins invite (email link, 7 days, single use, only for the invited address, token kept as a hash), change roles, remove members and open billing; only owners make owners, and the last owner can't leave. One person can be in several organizations (operators working for clients): the switcher at the top.
• Licenses: each organization's licenses, with the key, the public check link, status and the versions covered. "Licenses bought with your email" lists licenses whose email hash matches the signed-in user's verified email and that aren't in an organization yet, with "Add to ". Checkout stays guest-friendly: no account needed to buy.
• Billing: "Invoices and payment details" opens a Stripe customer portal session for the organization's Stripe customer (taken from the first license with a Stripe customer added to it, in the same mode as the key). Needs the key permission below; without it the page says it isn't available yet.
• Buy: the pack cards, with checkout through the same /api/checkout. On the console's host the route sees the session, so checkout gets the organization's Stripe customer (owners and admins; otherwise the user's verified email) and metadata.org_id, and the webhook issues the license straight into the organization. From the main site, checkout is exactly as before.
• Audit log: every write (and sign-in) goes into audit_log: actor, action, organization, target, time, details. Never tokens.
• users.is_admin marks Auto Tournament staff (the admin CRM). It follows ADMIN_EMAILS (below); don't set it by hand.

Retention (also in the privacy policy): expired sessions and sign-in links are deleted at startup and daily, invites 30 days after they are used, withdrawn or expired, audit log entries after 2 years, and contact form leads 24 months after their last activity.

Admin CRM (/admin)

console.autotournament.gg/admin (src/app/console/admin, logic in src/lib/admin), for the addresses in ADMIN_EMAILS only. A user whose verified email is in the list gets is_admin at sign-in and at startup, and loses it when the address leaves the list; every admin page, action and route also checks the list again, so a removal counts at once. Everyone else gets a 404, as if the pages weren't there. Without ADMIN_EMAILS nobody is admin. The console's header shows "Admin" to admins only. Every admin write goes into the audit log with the admin as the actor; signing and email actions are rate-limited (20 per 10 minutes).

• Overview: sales and revenue for the last 30 days and 12 months (EUR and NOK), the VAT threshold bar (the same sales and rate as the VAT alert), founder packs sold of 25 and days to 31 March 2027, licenses ending in the next 30 days, recent and unpaid orders, open leads, and the bookkeeping CSV.
• Licenses: search and filter; the detail page has the key, the public check link, organization, Stripe Dashboard links (built from the ids), email status, notes and history. Actions:
  • Reissue: signs a new key with the current LICENSE_SIGNING_KEY (new id, same email hash, organization and customer) and sets the old row's superseded_by. The old key keeps working offline; /verify shows it as "Replaced by ", and the console shows the newest key for that organization. An amount entered is the difference paid (it counts as a sale), never the original again.
  • Refund: gives the money back and records it. A card license: refunds the Checkout Session's PaymentIntent through Stripe (the whole amount left, or the amount typed, in the license's currency; reason requested_by_customer, duplicate or fraudulent; a note), after the browser's own dialog shows the amount and the license. A bank-transfer license: nothing is sent anywhere, it records the refund (amount, date, bank reference). A full refund marks the license (and its reissue chain) refunded, as below; a partial one keeps it valid and records refunded_amount, which revenue and the VAT total take off. Optionally emails the buyer a short "your license was refunded" note (Postmark, to the address it was bought with only). Never twice: the payment's refunds are read from Stripe first, the Stripe call has an idempotency key (refund:<license id>:<amount>:<refunded before>), and a double click in the same process is refused. 10 refunds per admin per hour. Needs Refunds: Write on the site's key (and Checkout Sessions: Read, part of the write permission it already has); without it the page says which permission to add. The webhook keeps it in step with Stripe: charge.refunded (a refund from here or from the Stripe Dashboard) records the charge's refunded total and, when it is all of it, marks the license refunded; a redelivered or late event changes nothing. refund.updated/refund.failed for a failed or canceled refund puts the amount back into revenue once and turns a "refunded" license into "revoked" (the key stays off; reissue it if the buyer keeps it). The license is found by the PaymentIntent stored at issuing, or for older licenses through Stripe's Checkout Session list. These audit entries have the actor stripe.
  • Mark refunded or revoke: sets revoked_at and the reason without moving money; never deletes. /verify says "Revoked", the console stops showing the key, and a refunded license leaves revenue, the VAT total and the founder count.
  • Resend license email: to the address it was bought with only (checked against the stored hash); for a card purchase it can read the address from the Checkout Session.
  • Notes (admin_notes), on licenses and organizations.
• New license (bank transfer / invoice): manual_orders. Paid: the key is issued at once into licenses (source = 'manual', with amount, currency EUR or NOK, and payment reference) and optionally emailed. Not paid yet: no key; "Mark paid" issues it. The buyer email is kept as a hash, like card purchases. Unpaid founder orders hold a place under the founder cap, which checkout and the pricing page count too.
• Organizations and Users: members, licenses, Stripe customer, notes; users with organizations and last sign-in (from the audit log).
• Leads: every /contact message is stored in leads as well as emailed (status new/replied/won/lost and a note; "Reply" opens your mail app). Deleted 24 months after the last activity (src/lib/db/prune.ts).
• Free LANs: the register of free LAN confirmations, from a lead or by hand.
• Audit log: filter by actor (email, user id or system) and action prefix.
• Bookkeeping export: /admin/export/sales?from=YYYY-MM-DD&to=YYYY-MM-DD, paid sales as CSV (date, license id, licensee, country, amount, currency, NOK amount, payment reference, rate). NOK amounts use Norges Bank's EUR/NOK rate of each sale's day (the business day before on weekends), fetched in one request; the latest rate if that fails.

Database

Postgres 17 runs as the db service in docker-compose.yml (volume db-data, not published on the host, health-checked; the website waits for it). The website gets DATABASE_URL from compose. Schema: src/lib/db/schema.ts (Drizzle ORM). After a schema change, run yarn db:generate and commit the new file in drizzle/; the app applies pending migrations itself at startup (src/instrumentation.ts), so a deploy needs nothing else. Look for [db] in the container log.

A backup, from your Mac:

ssh <host> 'docker exec autotournament-db pg_dump -U autotournament -Fc autotournament' > autotournament-$(date +%F).dump

Env

In .env next to docker-compose.yml on the server:

• POSTGRES_PASSWORD: the database password. openssl rand -hex 32 (hex, so it is safe inside DATABASE_URL). Required: without it docker compose refuses to build or start, so the running container stays as it is.
• AUTH_SECRET: at least 32 characters; signs Auth.js's cookies and hashes the email-link tokens. openssl rand -base64 48. Changing it signs everyone out and voids open sign-in links. Unset: the console says sign-in isn't available and /api/auth answers 404.
• AUTH_URL: https://console.autotournament.gg.
• AUTH_GOOGLE_ID, AUTH_GOOGLE_SECRET: the Google OAuth client (below). Unset: only the email link.
• POSTMARK_SERVER_TOKEN: as for the license email; the console sends the sign-in links and invites through it (tags console-signin, console-invite).
• ADMIN_EMAILS: comma-separated addresses that get the admin CRM, for example sivertgullberg@gmail.com. They must sign in with that address (email link or Google). Unset: nobody is admin.

ACCOUNT_SESSION_SECRET (the old /account page) is no longer used: remove it from .env. The old account.json next to licenses.json can be deleted.

For local development, a throwaway Postgres and .env.local:

docker run -d --name at-console-pg -e POSTGRES_USER=at -e POSTGRES_PASSWORD=localtest -e POSTGRES_DB=at -p 127.0.0.1:55432:5432 postgres:17-alpine
printf 'DATABASE_URL=postgres://at:localtest@127.0.0.1:55432/at\nAUTH_SECRET=%s\nAUTH_URL=http://localhost:4611\nSITE_URL=http://localhost:4611\nADMIN_EMAILS=you@example.com\n' "$(openssl rand -base64 48)" > .env.local
yarn dev   # the console is at http://localhost:4611/console; sign-in links are printed in the log

Setup (once)

1. Cloudflare tunnel: in the astro tunnel (Zero Trust → Networks → Tunnels → astro → Public hostnames), add console.autotournament.gg → http://dev.lan:31236, the same service as autotournament.gg. Cloudflare creates the DNS record.
2. Google OAuth client: Google Cloud Console → APIs & Services → OAuth consent screen: External, app name "Auto Tournament", support email, authorized domain autotournament.gg, scopes openid, email, profile only; publish it. Then Credentials → Create credentials → OAuth client ID → Web application: authorized JavaScript origin https://console.autotournament.gg, authorized redirect URI https://console.autotournament.gg/api/auth/callback/google. Put the client id and secret in AUTH_GOOGLE_ID and AUTH_GOOGLE_SECRET.
3. Stripe: give the site's restricted key Customer portal: Write (Developers → API keys → the key → Edit), and set up the portal once (Settings → Billing → Customer portal: turn on invoice history and updating billing details and payment methods; save). Until then the billing page says invoices aren't available yet.
4. Add the env vars above to .env and docker compose up -d. The first start creates the tables and imports licenses.json.

CS2 compatibility

/compatibility shows whether Ready Up works on the latest CS2 build: the verdict, each plugin's checks, the CS2 patch and build id, and recent runs. Ready Up's CI (cs2-update-watch.yml in the ready-up repo, contract in its docs/CS2-COMPAT.md) posts every run update, from queued to the verdict, to POST /api/compat/events. The page follows along live over server-sent events (GET /api/compat/stream) and polls every minute if the stream fails.

Public JSON: GET /api/compat/latest, GET /api/compat/runs?limit=20 and a shields.io badge at GET /api/compat/badge.json (https://img.shields.io/endpoint?url=https://autotournament.gg/api/compat/badge.json).

Set in .env next to docker-compose.yml:

• COMPAT_INGEST_TOKEN: the Bearer token the CI sends, at least 16 characters (openssl rand -hex 32). Unset means the ingest endpoint answers 404. In the ready-up repo, set the same value as the secret COMPAT_INGEST_TOKEN, and the variable COMPAT_INGEST_URL to https://autotournament.gg/api/compat/events.
• COMPAT_DATA_DIR (optional): where the runs are kept, default ./data/compat (/app/data/compat in the container).
• COMPAT_FEED_URL (optional): until the first push arrives, the site reads Ready Up's published compat.json from its cs2-build branch (at most every 5 minutes, keeping the last good copy). Set a URL to always read that file as well, or off to never read one.

The newest 200 runs live in one JSON file, rewritten atomically (temporary file, then rename). docker-compose.yml keeps it on the compat-data volume, so it survives rebuilds. Look for [compat] in the container log.

Still to do

• Record the product preview video and put it in public/preview.mp4 (the hero shows a labelled placeholder until then).
• An Open Graph image.
