 *
 * References ONLY shared token names (tokens.css §1–§5): --surface,
 * --surface-2, --paper, --border, --border-firm, --ink, --ink-2, --ink-3,
 * --accent, --accent-hover, --accent-soft, --chrome, --st-*, --radius-*,
 * --elev-*, --text-*, --space-*, --font-*, --motion-*, --focus-ring.
 * Never a legacy alias, never an app-specific class name.
