+### Phase 6: UX Polish
+
+**Goal**: Smooth the rough edges surfaced during live use — clearer all-day events, saner event-form date/recurrence behavior, recurring-series editing, and auth-flow polish — so the app feels slick for the non-technical Apple member (hard UX constraint).
+**Mode:** mvp
+**Depends on**: Phase 3 (calendar/event-form polish); Phase 4 for any list-related polish
+**Requirements**: TBD
+**Success Criteria** (what must be TRUE):
+
+  1. All-day events are visually distinct from timed events at a glance
+  2. The event form keeps a sane duration when the start moves, all-day edits don't grow the event, and a recurrence can be bounded (repeat-until / count)
+  3. A recurring series can be edited as a whole
+  4. A session that expires mid-use redirects cleanly to sign-in instead of hanging on a generic error
+  5. Unauthenticated cold load shows a neutral "signing you in…" splash — no calendar/"sign-in required" flash before Authelia
+
+**Candidate scope** (promote via `/gsd-review-backlog` at planning): 999.2 (login flash), 999.3 (session-timeout redirect), 999.6 (all-day visual), 999.7 (form end-tracking + all-day-edit off-by-one), 999.8 (recurrence bound), 999.9 (recurring-series edit). 999.4 (reminders) and 999.5 (provider setup) are more feature than polish — decide at planning.

 ### Pending Todos
 
 - **Fix `docs/deployment.md` local-dev command** — the documented dev run is wrong: the API dev script (`node --watch dist/index.js`) does NOT load `.env`, and `DB_HOST` defaults to `localhost` with an empty password. Correct local-dev command is: `pnpm --filter @familysync/api build && set -a; source .env; set +a && DEV_AUTH_BYPASS=true DB_HOST=localhost pnpm --filter @familysync/api dev` (+ `pnpm --filter @familysync/pwa dev`). Consider adding `--env-file=.env` to the dev script so this is automatic. (Surfaced during Phase 2 UAT.)
