Product backlog (return later)

Deferred and follow-up work from production UX review, catalog audit, and reliability findings. P0 is intentionally paused until we prioritize backend work.

P0 — Reliability (deferred)

• [ ] Supabase / Postgres pool stability — session pool exhaustion (max clients reached, pool size 15), statement timeouts, connect timeouts to pooler
• [ ] Monitoring — alert on /api/health ok: false on production alias
• [ ] Serverless DB client lifecycle — one pool per invocation, prefer transaction pooler where safe, idle release

P1 — Shipped (this branch)

• [x] Smoke bold catalog — transparent PNGs, catalog preview CSS (PR #45)
• [x] Wall templates — art display, manifestation, real life at guest / new wall entry
• [x] Auto-retry — API client retries once on 503/5xx (remote.js)

P2 — Shipped (this branch)

• [x] `···` menu dismiss — Escape and outside click
• [x] Favicon — public/favicon.svg
• [x] Explore sort focus ring
• [ ] Stray Explore chrome — verify on production after deploy
• [x] Mobile wall scale — min scale 0.58 + horizontal scroll on narrow viewports

P3 — Catalog & art

• [x] Smoke bold edge halos — despill + trim in knockout script (re-run npm run assets:knockout-smoke-bold)
• [ ] Cork cluster source art — fix black holes in embedded photos (needs Studio re-export)
• [x] Catalog tiering — Hero first; legacy sprites in collapsed “More sprites”
• [x] Extra templates: music corner, project HQ, memory board, night studio

P4 — Ops

• [x] Post-deploy smoke — node scripts/production-smoke.mjs (optional test account env vars for login step)
• [ ] QA uses production alias for account flows; preview URLs for UI-only with bypass
