- #/system/<section> renders the concept's System shell: section nav,
settings layout and Save row with truthful status (D92); each section
not delivered yet hands off to its legacy tools (D94). Overview's System
card opens #/system/overview (Q12).
- A module-level draft store saves browser, then host (expected_revision),
then runtime; failed domains stay dirty, a stale revision is a conflict.
- System row builders (setting, operation, section nav) on the scope.
- openReviewDialog and backupNotice extracted from the scan review, which
is now a thin caller with identical markup.
- Overview images gain a "rated" count (images whose linked prompt is
rated); the missing-files health check reports per source, so partial
availability is visible.
