/* Design tokens — CertStone "Night Console".
   World: a void-violet console lit by amber. Modelled on the owner's pinned
   reference (infinitytechstack.uk/pulsebridge), first shipped on the landing
   page 2026-10-20 and promoted site-wide the same day. Supersedes Warm Night
   (2026-09-12). Class names are unchanged from the previous worlds, so every
   template inherits this system without markup changes.
   Durable rules carried over: violet is the confidence band's alone; status
   is always glyph + words, never color alone; geometry encodes real numbers. */
