 * THEME LAYER PATTERN
 *
 * Dark mode is the default (:root). Light mode activates via
 * @media (prefers-color-scheme: light) when no JS override is
 * present, OR via [data-theme="light"] set by the JS toggle.
 *
 * Cascade priority:
 *   :root                                → dark defaults
 *   @media (prefers-color-scheme: light)
 *     :root:not([data-theme="dark"])     → auto light (no JS)
 *   [data-theme="light"]                 → manual light (JS)
 *   [data-theme="dark"]                  → manual dark  (JS)
 *
 * To add a new theme:
 * 1. Copy the [data-theme="light"] block below
 * 2. Rename to [data-theme="your-theme"]
 * 3. Override only the --nu-theme-* tokens
 * 4. Add the option to theme-toggle.js cycle
 * 5. Add the @media query if it should auto-detect
 *
 * Tokens to override (all required):
 *   --nu-theme-bg, --nu-theme-text, --nu-theme-heading,
 *   --nu-theme-muted, --nu-theme-surface, --nu-theme-border,
 *   --nu-theme-input-bg, --nu-theme-input-border,
 *   --nu-theme-accent, --nu-theme-accent-hover,
 *   --nu-theme-accent-subtle, --nu-theme-card-bg,

 *   --nu-glow, --nu-glow-hover
