modal store loads image detail (with neighbors) on open, exposes goPrev/
goNext that re-fetch the next image, and implements optimistic tag
remove with rollback on API failure. createAndAdd is the bridge between
the autocomplete UI and a brand-new tag.
usePanZoom is a small composable: click-to-toggle 2x zoom centered on
click point, wheel-to-zoom up to 4x, drag-to-pan when zoomed. Pointer
events are used (touch + mouse + pen unified). Caller spreads handlers
onto the element it wants pannable.
