 ## Phase 4: Touch Target Gaps & ContentPanel Tab Bar
 
-- [ ] **T14** — Fix ContentPanel.vue tab bar. Tab buttons likely have `gap-1` (4px) between them. Increase to `gap-2` (8px). Ensure each tab button has at least 44px height. The tab labels should use `text-xs` minimum (from Phase 1 fixes). The tab bar should be horizontally scrollable on mobile with sufficient padding.

-- [ ] **T15** — Audit and fix ALL remaining `gap-0.5` and `gap-1` between clickable elements. Search all `.vue` files for `gap-0.5` and `gap-1`. For each result, check if the container holds clickable elements (buttons, links, tabs). If so, increase to `gap-2` (8px). Leave non-clickable layout gaps (like text spacing) unchanged.

-- [ ] **T16** — Fix grid card touch targets. In all `*Grid.vue` components, verify that cards have sufficient tap area. Cards themselves are usually fine (full-width), but action buttons within cards (favorite, play, expand) need 44px targets. Check: `FilmGrid.vue`, `SongGrid.vue`, `BookGrid.vue`, `TVSeriesGrid.vue`, `PodcastGrid.vue`, `AppsGrid.vue`, `ArchyAppsGrid.vue`, `ImageGrid.vue`, `PlaceGrid.vue`.
