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.
