/* ============================================================================
   ONYX DNA — one stylesheet, no build step, role-based tokens. Dark only.

   THE STONE AND THE FIRE
   Onyx is a cut black stone with a violet fire inside it. This sheet renders
   that: a cool carbon-graphite mass (the stone), hairline steel edges (the cut
   facets catching light), and a single deep-violet signal (the fire) that
   appears rarely and means something every time it does.

   CANVAS  — carbon & steel. Cool-shifted neutrals, never pure black.
     --surface-0..3   elevation ladder: carbon -> graphite -> steel
     --line*          cool STEEL hairlines (rgba 203 213 225), not warm white
     --text / -mute / -dim   cool off-whites: bone -> ash -> steel

   SIGNAL  — violet, DISCIPLINED AND PRESENT. Logo-exact #844BF2 is the only
   brand colour, and the whole ramp derives from it (no other violet exists in
   this file). The fire is an earned structural throughline, not wallpaper:
       the brand mark · hero emphasis · key figures and labels · primary action
       · active/current state · focus · live cryptographic truth.
   Roughly 15–20% of accent moments carry violet. Carbon still dominates, but
   the logo now belongs to the interface rather than floating above it.

   STATUS  — a SEPARATE, graded functional channel, never blended with brand:
       LIVE --ok green · DEAD --bad red · WARN --warn amber. Always paired with
       an icon or word — never colour alone. Graded for AA on carbon.

   MATERIAL — machined with a restrained float. Depth is surface-value steps,
   a 1px steel edge-light, quiet carbon shadows, and the occasional violet edge;
   never consumer glow or gradient. Facets stay crisp inside softened geometry.

   PRIMITIVES that make a view "Onyx" (compose, do not decorate per page):
       .facet          cut panel: steel body, hairline, corner ticks; --live adds
                       the violet edge-light (the facet catching the fire)
       .console-header [LABEL] mono header trailed by a hairline rule
       .readout        KEY ········· value  (coordinate/registry metadata)
       heartbeat       the canary indicator, motion tied to real state
