# NEXT_PUBLIC_POSTHOG_KEY comes from a repository variable: `vercel pull`
# writes the literal "[SENSITIVE]" for env vars flagged sensitive on
# Vercel, and that string was compiled into the bundle as the PostHog
# token (no event reached PostHog from 2026-08-24 to 2026-09-20).
# process.env wins over the pulled .env file. The token is public by
# nature (it ships to every browser), so a variable, not a secret.
