   Semantic note — token naming history

   Legacy `--purple` is a misnomer: the current brand color is gold (#E8A020),
   not purple. Use `--brand-gold` (and the `--brand-gold-*` family) going
   forward. `--purple`, `--purple-light`, `--purple-glow`, `--gold`,
   and `--glow-gold` remain as backwards-compat aliases pointing at the
   canonical `--brand-gold*` tokens — 60+ files still consume them.
   `--glow-gold` previously held a TEAL value; it has been corrected to
   actually be a gold glow. Components that intentionally want a teal glow
   should switch to `--brand-glow-teal`.
