/* Pigeon site tokens. The real brand (docs/brand/BRAND.md, 2026-10-24):
   Pigeon Purple, Black, Sky Blue, Pink, Mist, Orange. Black is the website's
   ground, Mist its text, Purple the call-to-action fill, Sky Blue links and
   focus; Pink and Orange mark state and the odd highlight, nothing else.
   The neutrals lean cool, Mist's way (red <= green <= blue; black is the
   limit case). The light theme is the same palette on white.
   This is the only site file allowed a colour, a length or a font name
   (scripts/site/check.py holds the rest to that).
   Black is the default: it is :root. Light applies only when the visitor
   ticks the theme switch, which needs no script and stores nothing. */
