Problem
Several components exist but aren't wired up, and there are minor style inconsistencies:
`ai/SearchResults.svelte` — exists but not referenced anywhere
`TagTree.svelte` — built but not used in any route
`entries/clip/+page.svelte` uses `gray-` Tailwind classes instead of `zinc-`
`starred` store uses a composable function pattern while all other stores use class singletons
`renderMarkdown` function in entry detail is dead code (identified in ux-accessibility-fixes)Solution
Delete or defer unused components (SearchResults, TagTree) — or wire them up if they're needed
Fix `gray-` → `zinc-` in clip page
Align `starred` store to class pattern or document why it's different
Delete dead `renderMarkdown` function
