### Added
11
+
- Slides mobile panel toggle: on phones (<=480px) the slides thumbnail panel was previously hidden with `display:none` and no way to bring it back, making slide navigation impossible. A new `btn-toggle-slide-panel` in the slides topbar now flips a `.slides-panel--mobile-open` class that renders the panel as a full-height overlay so users can jump to any slide. Tapping a thumbnail or hitting Escape closes the overlay. (#688)
11
12
- Shared export/import toast helper (`src/lib/export-feedback.ts`): `exportSuccess`/`exportError`/`importSuccess`/`importError` centralize user-facing copy with built-in noun pluralization and Error-message extraction, so every editor's export path surfaces the same phrasing ("Exported 12 rows as CSV", "CSV export failed: bad quote") instead of each editor re-implementing feedback. 12 unit tests pinning the contract. (#686)
12
13
- Slides: JSON deck export — the previously dead "Export" button in slides now downloads the full deck state (slides, theme, transitions, animations) as a `.deck.json` file. Enables backup/clone-a-deck workflows until native PPTX/PDF export lands. (#686)
