 /* ============================================================
- * COLOR THEMES
+ * THEMING — two orthogonal dimensions
  *
- * 5 dark themes sharing structure, swapping only the primary
- * accent (and a tiny hue rotation on the slate base). Switched
- * at runtime by setting `document.documentElement.dataset.theme`
- * — see ThemeProvider + the inline boot script in layout.tsx.
+ *   1. MODE   (light / dark)  → neutral surfaces. Selected with
+ *      `document.documentElement.dataset.mode`. Defaults to dark.
+ *   2. ACCENT (violet / …)    → the primary color only. Selected
+ *      with `document.documentElement.dataset.theme`.
  *
- * `:root` mirrors Violet so default visitors render correctly
- * before JS runs. `[data-theme="violet"]` is included for the
- * explicit-select path (settings UI sets it after a pick).
+ * The two compose: any accent works in either mode. Neutral
+ * tokens (background / card / border / muted / sidebar surfaces /
+ * neutral charts / radius) live in the MODE blocks below; accent
+ * tokens (--primary*, --ring, --chart-1, --sidebar-primary*,
+ * --sidebar-ring) live in the ACCENT blocks. They set disjoint
+ * variables, so cascade order between them doesn't matter.
  *
- * The three `--primary-*` extras (hover / soft / soft-2) are
- * new — used for hovered primary buttons and tinted-primary
- * surfaces (sidebar active pill, validation badges). Components
- * that don't use them remain backward-compatible.
+ * `:root` carries the dark-mode + violet defaults so a visitor
+ * renders correctly before JS runs; the boot script in
+ * layout.tsx replays the saved mode + accent before first paint.
+ *
+ * The three `--primary-*` extras (hover / soft / soft-2) feed
+ * hovered primary buttons and tinted-primary surfaces (sidebar
+ * active pill, validation badges).
  *
  * Token shapes come straight from the design handoff at
  * project/Color Themes.html — change one, change the other.
