Closes #171

What changed

  • Background (components/layout/background.tsx): second gradient blob from opacity-90 down to the first blob's level (opacity-10 light / opacity-20 dark, first blob matched). Animated squares peak at 10% instead of 30% and fade to a quarter of that under the content column via a horizontal mask (they keep the grid's radial mask too). The watermark is a bit softer in light mode. Squares aren't rendered at all under prefers-reduced-motion. Grid, blobs, and watermark are all still there.
  • About: removed the "I'm an active open-source contributor…" paragraph from ABOUT_BIO, which also drops it from the chatbot context.
  • Open Source: removed undrstnd-labs/education and undrstnd-labs/developers from REPOSITORIES (grid goes from 10 to 8).
  • Contributing to: the "Write-up" text link is now the existing Icons.post document icon, with aria-label and title set to "Read the write-up". Added:
  • Photo cards (about-overview-card-stack.tsx): spring flip with a slight overshoot, pointer tilt on hover (mouse only, ±7°), and a radial glare that follows the pointer and sweeps across the face during the flip. Each face also darkens as it turns edge-on. A blurred shadow plate under the card narrows with |cos θ| and slides sideways during the flip, then deepens while you drag. The outer card no longer clips 3D or paints a flat background, so mid-flip the silhouette really turns. Under reduced motion the flip is instant and tilt is off.
  • Stamps (about-overview-stamps.tsx): two photo stamps (Kapadokya, Jbal Rsas, using public/about photos with a light sepia so they don't compete with the cards), one typographic "Monastir 500 millimes" stamp, and a circular postmark. Edges are perforated with a CSS mask (a radial-gradient tile plus a solid inner layer). Each stamp gets a small random offset and rotation after mount, so there's no hydration mismatch. They're aria-hidden, pointer-events-none, and absolutely positioned inside the existing square box, so there's no layout shift. They stay behind the cards.
  • GitHub graph: the calendar scrolls to its right edge in a layout effect, so narrow screens open on the most recent weeks. Streak cells stay amber, but fill-opacity now scales from 35% to 100% by level.

Background readability research

  • WCAG 1.4.3 (AA) asks for 4.5:1 for body text against the background "in normal usage", and failure technique F83 covers background images and patterns that drop below that. For a gradient or pattern, the bar is the worst-case region behind the text, not the average.
  • WCAG 2.2.2 (Pause, Stop, Hide) covers decorative motion too: anything that starts automatically, lasts more than 5s, and plays next to other content needs a way to stop it. The squares loop forever, so they now honour prefers-reduced-motion. Separately from conformance, moving shapes in peripheral vision pull attention away from reading, so the change both lowers their peak and keeps them out from under the text column.
  • What comparable dev portfolios and Tailwind-style hero backgrounds do: grids at about 5–10% stroke, radially masked away from the reading area. Glow blobs stay at about 10–30% opacity and sit near the hero or edges, not under paragraphs. Any motion lives in the gutters. Text columns stay effectively solid. That's the direction taken here, without replacing the existing design.

Measured with a headless browser at 1440×900: everything except the background layer was hidden, the content column was sampled over about 9s of square animation, and 1px grid hairlines were excluded. Numbers are the worst-case contrast at any point:

body text (old → new) muted text (old → new)
Light 12.66 → 17.82 2.96 → 4.17
Dark 8.64 → 13.56 3.68 → 5.77

Body text passes everywhere in both modes. Muted text passes everywhere in dark mode. In light mode it only dips below 4.5 at the brightest spot of the cyan blob near the top-right of the header. For reference, the --muted-foreground token is only 4.61:1 on plain white, so any visible tint behind it lands just under AA. Fully fixing that means darkening the token, which is out of scope here and would make a good one-line follow-up.

Screenshots

I checked the homepage at 1440px and 390px in light and dark mode, plus close-ups of the card stack (idle, hover tilt, mid-flip, reduced motion), the contribution graph on mobile (opens on Sep, with the streak showing as an intensity scale), and the contributions hover cards (document icon on the Databuddy write-up, new WalletLabels and uniswaphooks entries). No hydration warnings showed up with reduced motion on.

Checks

  • pnpm lint: 0 errors. The only warnings are already on main, in files this PR doesn't touch.
  • pnpm build: passes.

Summary by CodeRabbit

  • New Features
    • About cards now feature interactive 3D flips, tilt, and layered effects.
    • Interactive stamps share personal stories, can be placed on page sections, and remain saved between visits.
    • Project write-up links are presented as accessible icon controls.
  • Improvements
    • Animations respect reduced-motion preferences, and decorative page elements are more subtle.
    • Contribution graphs show the latest weeks first on narrow screens, with streak intensity reflecting activity.
    • Contribution project listings have been updated, and contribution data failures now leave the page usable.
  • Content Updates
    • The About overview no longer includes its paragraph listing open-source contributions and projects.

Second gradient blob drops from 90% to the same faint wash as the first
(lighter still in light mode), the animated squares peak at 10% instead
of 30% and fade to a trace under the content column, the watermark is
softer in light mode, and the squares are skipped entirely for
prefers-reduced-motion.
…te-up link

Removes undrstnd-labs/education and undrstnd-labs/developers from the
Open Source grid. Adds function03-labs/WalletLabels (#15, #22, #20, #19)
and function03-labs/uniswaphooks (#1), all merged PRs by FindMalek in
public repos. The text Write-up link becomes a document icon labelled
"Read the write-up".
Spring flip, pointer tilt, moving glare, face shading while edge-on, and
a shadow plate that narrows and slides with the rotation. Reduced motion
gets an instant flip and no tilt. A few perforated stamps and a postmark
sit behind the stack, scattered slightly after mount.

📝 Walkthrough

Walkthrough

The homepage changes add interactive, persistent About stamps and card effects. They also adjust background rendering, contribution displays, contribution records, and cached contribution error handling.

Changes

Homepage updates

Layer / File(s) Summary
Stamp data and About integration
config/about.ts, components/app/about-overview.tsx, components/app/about-overview-cards-stack.tsx
The About configuration adds three stamp stories and removes the open-source contributions paragraph. The stamp hint appears beside social links, and the stamp component renders inside the card stack.
Stamp placement and sound
components/app/about-overview-stamps.tsx, lib/stamp-sound.ts
Visitors can open stamp stories, place stamps on page sections, remove placements in the home area, and reset saved placements. Placement data uses local storage with in-memory fallback. Stamp actions can play synthesized sounds.
Card motion and lighting
components/app/about-overview-card-stack.tsx
Cards add spring-driven flips, pointer tilt and lighting, animated shadows, and drag indicators. Flip and indicator motion account for reduced-motion preference.
Contribution graph and link display
components/app/contribution-graph.tsx, components/app/github-contributions.tsx, components/app/project-contribution-card.tsx
The contribution calendar scrolls to its right edge on layout and width changes. Streak opacity scales with activity level. The write-up link becomes an icon control with an accessible label and title.
Contribution records
config/consts.ts
The repository list removes two entries and adds contribution records for WalletLabels and uniswaphooks.
Background rendering and motion
components/layout/background.tsx
Animated squares render only after mount and when reduced motion is not preferred. A horizontal mask is added, and selected opacity values are reduced.

Contribution fetch handling

Layer / File(s) Summary
Cached contribution request handling
lib/get-cached-contributions.ts
The cached request uses an eight-second timeout. The exported function logs a warning and returns an empty array if the request rejects.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Feature · Severity of issue fixed: Low

Merge Risk: 🔵 Low · up to 509c6

The homepage polish can be merged once the owner is aware of two small open items. Card drag animation still runs when reduced motion is preferred. The contribution graph may also stop showing the newest weeks if the window narrows after the page loads. Neither issue blocks normal use.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 509c6

The inspected changes keep saved stamp interactions within browser presentation state and use existing GitHub integrations for contribution data. No material security regression was identified. The assessment is limited by incomplete security coverage and deployment evidence.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated exposure of manipulated placement records is browser-origin presentation state. Configured stamp identities and content remain authoritative; no inspected placement path transmits records to a service or grants access to another user's server-side assets.

Trust Boundaries and Controls

  • observed — Stored placements are treated as unknown data, parsed defensively, and accepted only for configured stamp IDs with the required primitive field types. Arbitrary anchors reach getElementById rather than an attacker-built selector, and displayed strings use React text rendering. Validation does not establish finite coordinate bounds, valid dates, or anchor membership.

Resilience and Maintainability Implications

  • observed — Failure containment is explicit in the inspected paths: malformed or inaccessible storage falls back to empty placements, pointer events are matched to the active pointer, and event listeners, resize observers, animation frames, and temporary cursor changes have cleanup paths. Contribution fetch exceptions are contained before reaching the homepage consumer.

Explanation

Most #171 objectives are implemented, including quieter background effects, content removals, contribution updates, card effects, and graph behavior. The stamp implementation does not meet #171. The issue requires decorative stamps that are aria-hidden and do not intercept pointer input. AboutOverviewStamps adds pointer drag and click behavior, story labels, persistent placements, autoscroll, audio, and vibration. The inspected code registers global pointermove, pointerup, and pointercancel handlers and calls swallowNextClick() after a drop.

Resolution

Change the stamps to decorative elements only. Set the stamp layer to aria-hidden="true" and pointer-events: none. Remove drag, click/story, persistence, autoscroll, audio, vibration, and placement behavior. Keep only the requested fixed, non-layout-shifting decorations with hydration-safe jitter.

Full details: Out of Scope Changes check

Explanation

The PR contains changes outside #171. The stamp feature adds an interactive placement system with local storage, section anchoring, drag autoscroll, story UI, audio synthesis, and vibration, although #171 explicitly limits stamps to decorative elements. lib/get-cached-contributions.ts also changes third-party fetch timeout and error handling. That change is unrelated to the requested graph scrolling and streak opacity behavior.

components/app/about-overview-stamps.tsx (1)

47-50: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Key HOME_SPOTS by the stamp ids so a missing entry fails at compile time.

HOME_SPOTS has the type Record<string, …>. Line 607 reads HOME_SPOTS[stamp.id], and Line 609 then reads spot.rotate without a guard. Suppose a new entry is added to ABOUT_STAMPS in config/about.ts with no matching HOME_SPOTS key. spot is then undefined and the whole About section throws while rendering. TypeScript does not catch this because Record<string, …> treats every key as present.

The fix is to give the stamp ids a closed union in config/about.ts and key HOME_SPOTS by that union. With this change, a missing entry fails pnpm build and does not crash at runtime.

♻️ Proposed refactor

In config/about.ts:

export type AboutStampId = "hair" | "artweave" | "qorelo"

export type AboutStamp = {
  id: AboutStampId
  // ...
}

In this file:

-const HOME_SPOTS: Record<
-  string,
-  { className: string; rotate: number; labelSide: LabelSide }
-> = {
+const HOME_SPOTS: Record<
+  AboutStampId,
+  { className: string; rotate: number; labelSide: LabelSide }
