/* Colour, type, space, motion, elevation and layer names all come from
   tokens.css, which is loaded before this file. There is one vocabulary now:
   the phase-1 aliases (--bg, --line, --text, --muted, --quiet, --accent,
   --body, --display) are no longer read anywhere below, so tokens.css can drop
   them whenever Designer likes.

   Two deliberate exceptions, both of which keep this file readable:

   - the `font:` shorthand stays literal. Bundling weight, size, leading and
     family is the point of the shorthand; splitting it into four var() calls
     costs more than the names are worth. The family is still a token.
   - optical in-betweens stay literal, the way tokens.css says the space scale's
     do: a 9px radius or a 14px one is a judgement about a specific corner, not
     a step on a scale, and forcing it onto one would be a lie about the system.

   Every other value here is a token. The migration was checked by resolving
   both files' var() chains before and after: it changed the computed value of
   no existing declaration. Rules added since — the overlay's safe centring and
   the phone spacing below it — are new declarations, not changed ones. */
