`IntegrationsSettings/index.tsx` has carried the rule since email was extracted
on 2026-08-18: a plugin contributes panels, not settings sections. the
extraction brief said the opposite and the brief was wrong.
settings living in the platform mean this plugin is not self-contained — it
cannot be configured on an older platform, and uninstalling would leave a dead
"Atelier" section in the settings screen for someone to delete by hand.
so: a fourth panel, `atelier-providers`, and the default layout stacks it under
Collections in the right column. smallest and last because it is configured once
and then ignored — but it has to be REACHABLE, which is the whole point.
Generate's empty state pointed at "Settings → Integrations → Atelier". it now
points at the Providers panel, which is where the key actually goes.
ported from the standalone app's hash-tab UI. The panels do not coordinate through props (the panel
contract only ever hands a component its panelId) or usePanelChannel-as-selection:
- Gallery's lightbox is ?selected=<id>, Collections' detail is ?collection=<id> — different names
since both panels render on the same route at once
- Generate bumps useAtelierRefresh (added to officerdev/src/channels.ts) when a job finishes;
Gallery subscribes to it — a genuine signal, not a selection, so it stays a channel
images render through GET /files/:filename with a ?token= query param appended client-side
(lib/api.ts's fileUrl), the same escape hatch FileViewer and the music plugin use for exactly this:
a browser cannot set an Authorization header on an <img src>.
Providers is not here — see PLUGIN.md for why it became a platform settings screen instead.
assets/icon.png and assets/splash.png are [placeholder] flat swatches, not real artwork — see
assets/PLACEHOLDER.md.
