     DESIGN TOKENS

     Every colour, alpha overlay and typeface on the site resolves to a
     token below. Nothing downstream hardcodes a value, so a restyle is a
     change to this block rather than a sweep through four stylesheets.

     The *-rgb tokens exist so translucent variants follow the palette:
     rgba(var(--violet-rgb), 0.18) tracks --violet, a literal does not.
