/* Forgeworks / Anvil — design tokens (ANVIL-BRIEF.md §4).
   The single source of truth for color, type, space, radii, elevation and
   motion. Loaded before index.css (see main.jsx) so every rule resolves
   against these. Dark is the default theme; light is a full value-set swap
   on the same names (§4.3). Density swaps token VALUES, never components. */
