   - Non-color tokens (radius, fonts) live in :root.
   - Color tokens live in html[data-theme="dark"] / html[data-theme="light"].
   - JS (assets/theme.js + an inline head script) resolves the active theme
     (dark/light) from the saved preference (localStorage `emailops_theme`) or
     the system `prefers-color-scheme`, and sets `data-theme` before paint.
   - :root carries a dark fallback so the UI is usable even if JS is disabled.
