- LiveView: localStorage pins carry image URLs, so they rendered (without credit) after an admin disabled the provider. Pins now show only while their provider is serving (server-26#198 licence gating). - MapView: pinned/docked map players drop out once their provider leaves the serving list; credits are kept from the last answer so docked players keep attribution while the overlay is hidden. - WallPanels: the "no camera provider enabled" link to /admin was a dead CTA for non-admins (bounced to /). Link shown to admins only, deep-linked to /admin#cameras; the admin page now honours a tab hash. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
