/* BIND visual system. Colours live in tokens.css only (sampled from the brand assets); this file reads variables.

   World: lavender-white paper, navy ink, one dark "night" seal. Brand hues (green, lavender, indigo) mark things:
   green = live and settled, lavender = mist surfaces, indigo = emphasis. State never rides on hue alone:
   live is a solid dot, stale a half dot, unread a hollow dot.
   Shape rule: buttons, chips and state chips are pills; cards 16 px; shells 24-28 px; inputs 12 px.
   Tap rule: every control is 48 px tall on phones and coarse pointers.
   z scale: 1 pinned stage, 50 bar, 80 skip link. */
