/* MailLama website on Meridian: islands on a neutral ground, violet spent on
   intent, Inter for chrome and a serif for message bodies, as in the app.
   Colours are Meridian's tokens with the `crossproton` brand (light and dark).
   The ivory Lama only ever sits on the brand ground (--brand); everywhere
   else the family signature is painted in ink-faint. Pages work without
   JavaScript; site.js adds the hero scene and the interactive models. */
