// My QBZ — Rename / Description / Delete-confirm modals (spec 12 §11).
//
// Driven from the hero overflow (⋯) menu. A single global (MyQbzEditState)
// backs all three; `mode` ("rename" | "description" | "delete") selects which
// body renders. Chrome mirrors EditPlaylistModal / CreateMyQbzModal: a 420px
// panel, h2 title (18px bold), the m-input field family, and an m-footer with
// secondary Cancel + a primary/destructive submit. Backdrop click + Cancel
// close without committing; Enter submits the rename. Submit is disabled while
// busy or (rename) the trimmed name is blank.
//
// Per spec §23 the Cancel / Save button labels are HARDCODED in the Tauri
// source; we keep them @tr here (DQ2 — translate hardcoded UI strings on port).
