AppSnackbar mounts once at the app root and exposes a window.__fcToast
function the stores call from error paths. This avoids prop-drilling a
toast emitter through every component while keeping the snackbar
component itself testable in isolation.
GalleryGrid renders shimmer-skeleton placeholders on initial load so the
first paint isn't empty. Skeleton uses the same auto-fill grid columns
as the real items so layout doesn't shift when content arrives.
Modal arrow nav now ignores text-entry elements so typing in the tag
autocomplete doesn't navigate prev/next. Small-screen breakpoint
(<600px) tightens gallery thumbnails to 120px min.

Teleport mounts the modal under <body> so it can break out of the
gallery container's stacking context. Body overflow is locked while open
so background scroll doesn't compete with pan/zoom.
Keyboard: left/right arrows navigate prev/next (preventDefault so they
don't also scroll the body), Esc closes, Tab is trapped within the
modal by browser default since the modal is focused on mount.
TagPanel renders kind-colored chips with the close (×) affordance for
removal, and hosts TagAutocomplete + FandomPicker for additions. Below
900px the panel drops below the media area instead of beside it.

GalleryView wires the grid + timeline + modal together. The URL is the
source of truth for which image (if any) is open — clicking an item pushes
?image=N; closing the modal pops it. This makes deep links shareable and
the back button work intuitively.
Below 900px viewport, the timeline drops below the grid as a horizontal
strip so it doesn't compete with thumbnail space on mobile.
Modal store + ImageViewer are placeholders here; real implementations land
in Batch 5 (Tasks 19–22).
