+- [x] **#10 Unify grid breakpoints** — new `<FlavorGrid>` (`components/ui/FlavorGrid.tsx`) is the single source of truth for flavor-card grids: default roomy auto-fill mode + `compact` 2→6 fixed mode. Replaced the 3 divergent inline `display:grid` defs (CategoryFlavors, MainPage search/newest) and converted SimilarFlavors off MUI `<Grid>`.

+- [x] **#12 Font-weight scale** — normalized all inline weights to a numeric scale (`'bold'`→700, `'900'`→900, `'800'`→800) across 35 files; theme typography already owns h1–h6/button/tab weights. No visual change (`'bold'`===700).

+- [x] **#14 Image placeholder** — new `<FlavorThumb>` (`components/ui/FlavorThumb.tsx`) renders the flavor initial on missing **or** failed image (`onError` fallback), no broken-image glyph. Adopted in `CommunityFeed` (feed + top-followed) and `MyReviewCard`.
+- [x] **#15 Standardize empty states** — audited: all user-facing list/section empties already use `<EmptyState>`. Remaining inline `<Typography>` are intentional in-card comment placeholders (italic "no comment") + one admin-only caption (deferred under #1).
