GalleryAuthContext cached the event in sessionStorage on first visit and
then SKIPPED the server fetch on returning visits (`if (!storedEvent)`),
so a guest who'd already opened the gallery would never see admin edits
to welcome_message / event_name / hero_logo / colour theme — sessionStorage
survives Cmd+Shift+R, so the only escape was closing the tab or wiping
site data manually.
The cached event is still shown above as an instant placeholder for
perceived perf, but the server fetch is no longer gated: on every mount
the fresh row overwrites both React state and the sessionStorage entry.
Cost is one extra /gallery/:slug/photos request per gallery navigation
when the session is already authenticated; benefit is admin edits
propagating on next page load for everyone.
