+## [2.2.0] — 2026-06-13
+
+### Added
+- **View Transitions** — Native cross-fade on theme switch and central modals (Settings, Theme-Picker, custom dialogs, bookmark import, add-board, add-bookmark, rename). Feature-detected via `document.startViewTransition`, instant swap on older browsers. Widgets, notebook sidebar and onboarding deliberately excluded.
+- **`color-scheme: dark`** — Declares the dark UA scheme so native scrollbars and form controls match the dark themes.
+- **Accessibility pass** — `role="dialog"` / `aria-modal` / `aria-labelledby` on Settings and Theme-Picker with new focus trap, Escape handling and focus return; `role="toolbar"` + per-button `aria-label` on the widget toolbar; keyboard-operable theme cards (`role="button"`, `tabindex`, Enter/Space); `role="switch"` + `aria-checked` on settings toggles; focusable boards and bookmarks; visible `:focus-visible` ring tinted in the theme accent. New ARIA strings run through the i18n pipeline. Verified with Lighthouse and the axe DevTools extension, not a formal WCAG 2.2 AA audit.
+
+### Changed
+- **`color-mix()` token refactor** — Accent-derived color tokens now computed via `color-mix()` from `var(--accent)`, classified per theme (formula vs. override). Theme-specific alpha values and real special colors stay overrides; no visible theme change. `--border-accent` `:root` drift (179,92,255 → 179,89,255) fixed at both the Nebula block and the `:root` default.
+- **`@layer` cascade ordering** — CSS reorganized into six layers (base / theme / layout / components / theme-overrides / utilities) so theme component overrides win deterministically instead of relying on selector specificity.
+- **`clamp()` fluid typography** — Clock, logo, board titles and main spacing scale fluidly via `clamp()`. Existing 768px / 480px breakpoints kept as a safety net.
+
+### Accessibility
+- **`prefers-reduced-motion`** — Unlayered `@media` block disables transitions and animations, including the `::view-transition-*` pseudo-elements. The 350ms widget teardown fallback timer is retained so widgets still close when `transitionend` no longer fires under reduced motion.
