Adds a right-hand "Configure" slide-over to each Auto-Tune Preview row, making
a proposed channel editable before bulk-create — against the shipped #384/#385
backend only, so no control lacks a wire target.
- New reusable SlideOver primitive (components/overlay.tsx), sharing a
useOverlayBehavior hook (focus/scroll-lock/Escape/scrim) with Dialog.
- Extract the Channel Builder's advanced-options model to builder/advancedOptions.tsx
(enum catalogs, ADVANCED_KEYS, effectiveValue, INHERIT/omit useAdvancedOverrides
hook); ChannelBuilder imports it unchanged (its tests pass byte-for-byte). The
DetailPanel writes its own field JSX over the same hook — shared logic, per-screen
layout.
- Panes: identity (name/number + logo upload), Playback (Shuffle/Always-playing →
advanced.playbackOrder/playoutMode), per-channel template picker, Advanced
disclosure, lean read-only Query&size, read-only Content-sources via GET /members.
- getAutoTuneChannelMembers API client (#384 read endpoint) + tests.
- Screen-scoped §8 unsaved-changes guard + "Edited" row badge.
- Dropped as backend-less decoration: MiniEpg, bug-initials generator, query text.
Deferred to #425 with an in-pane hint: per-source weight steppers + corrections.
- Docs: spa-conventions §11 (SlideOver + shared advanced-options), decisions.md.
