pagehide so Chromium tab suspension cannot drop pending debounced saves.
Restore cached draft over saved memo content when they differ (inline editing).

Keep the unpublished image-sharing flow scoped to memo detail pages.

- add a dedicated share-image preview and export pipeline
- measure the rendered memo card so preview and exported image stay aligned
- move the entry point into the detail sidebar and drawer only

- split attachment page states and primitives into focused components
- unify card and list item presentation across media, audio, documents, and unused uploads
- move attachment paging and cleanup flows onto shared query and view-model hooks
