 - **Architecture notes (low priority):** deep `features/` + `hooks/` nesting, many small coupled hooks, possible dead CSS/components, `SpacingVariant` / `DropTarget` recipe simplification.
 - **Git workflow (forward-looking):** keep commits scoped — past monolithic "fix all bugs" commits and inconsistent prefixes hurt `git bisect`.
 
-### Native-Cinny polish (remaining from the design-law audit)
-
-The "renders-broken-on-stock-themes" cluster (ungated invented CSS vars across
-~13 files + the toast rebuild) is fixed; Sentry was removed. Lower-priority
-pattern items left:
-
-- **Profile timezone `<select>`** (`settings/account/Profile.tsx`) — still a raw native select (`colorScheme:'dark'`); it's wired to native form submission + a disabled state, so converting to `SettingsSelect` needs care.
-- **MediaGallery lightbox** (`room/MediaGallery.tsx`) — raw `<div role="dialog">` + `#fff`/rgba chrome over forced-black media. Should be folds `Overlay`/`Modal`; the over-media light-on-dark scheme is a borderline-justified scrim.
-- **Nits:** scattered `opacity:` → `priority`, the poll `✓` Unicode glyph → folds `Icon`, a few `zIndex` magic numbers.
-
 ### Big Projects
 
 - **#5 — Seasonal themes & chat-background redesign.** Current backgrounds are basic CSS; goal is high-fidelity, research-backed, GPU-accelerated designs (layered `oklch`, `backdrop-filter`, `contain:paint`) with WCAG-AA overlay contrast. Treat each as its own design sprint.
