No error.tsx existed anywhere in the app - an uncaught render error on
any page (a beekeeper's most field-critical moment: mid-inspection,
no signal, nowhere to go) showed nothing recoverable, not even a
message, let alone a way back to a working page.
Two boundaries, matching Next.js App Router's error-boundary scoping:
- (app)/error.tsx covers every authenticated page. It only replaces
the crashed page's content - the sidebar/header/bottom nav stay
mounted and usable, so the user can navigate to a different page
without a full reload.
- app/error.tsx is the outer fallback (login, the public Herkunft
page, or a crash in (app)/layout.tsx itself, which only a strictly
higher boundary can catch). Its "Zum Dashboard" action is a plain
<a> reload rather than client-side navigation, since a crash this
high may have left client state corrupted.
Both are in German, matching the app's existing card/honeycomb visual
language, and explicitly reassure the user that already-saved data is
unaffected.
