// Inkwell — shared curation controls (TK-12241).
// Per-card: a select checkbox + two big full-width buttons (Approve / Delete; Restore when deleted).
// Per-section: a sticky bulk bar that appears once >=1 card is selected (Approve N / Delete N /
// Select all / Clear). Delete always goes through an in-page confirm modal (never window.confirm).
// The server is the source of truth: every POST returns the collection's items, which replace the
// local copy before re-rendering.
