- Xtream and Stalker `:categoryId` routes carry a parental-lock guard: a
locked category reached by URL prompts for the PIN and redirects to the
section root on refusal (Electron row ids are mapped to provider ids).
- PWA search filters withheld categories like the catalog reads.
- Electron warm-cache detection confirms an empty, lock-filtered read with
the unfiltered existence check instead of refetching from the provider.
- A Stalker lock flip past page 1 drops withheld rows at once and restarts
the list from page 1 instead of appending onto stale pages.
