Installs all five Tier 2 polish deps the audit flagged. Each integrates
where it adds concrete value today:
- **embla-carousel-react** — shadcn-style `<Carousel>` primitive in
`src/components/ui/carousel.tsx`. Available for future berth/yacht
photo galleries; no current call site beyond the primitive.
- **yet-another-react-lightbox** — wired into the image branch of
`file-preview-dialog.tsx`. Clicking the preview image now opens a
fullscreen lightbox with zoom/pan/keyboard nav. Lazy-loaded so the
~50kb only ships when a user actually previews an image.
- **@use-gesture/react** — `usePinch` on the PdfViewer's content
pane for native pinch-zoom on tablets/phones. Clamped to the
same [50%, 300%] range as the +/- buttons; desktop wheel still
scrolls.
- **react-virtuoso** — installed but NOT wired. Inbox is naturally
bounded by recent-notifications filter at ~10-20 items; ScrollArea
handles it fine. Reserve for actual scale issues (admin audit log
archive, etc.).
- **motion** — installed but NOT wired. Pipeline kanban uses
dnd-kit's own transforms and conflicts with motion's layout
animation. @formkit/auto-animate already handles list-mutation
animations elsewhere. Available for opportunistic adoption when
a polish surface emerges that the existing libraries don't cover.
Verified: tsc clean, vitest 1315/1315, next build green.
