/* YewForge "ember ring" design system (direction B, chosen 23 October 2026).
   Pages opt in with <body class="ember">; every other page keeps its old stylesheet until rolled out.

   Rules of the system
   - Ground Bone, ink Charcoal. Ember is only the ring and the primary action. Small text on Bone that
     needs a warm colour uses Ember Deep (4.5:1 or better); Ember on Bone is decoration only.
   - The half-ring from the YewForge mark is the one motif: button radius (square left, round right),
     list bullets, image crops, section dividers, and the full ring that draws once on the hero.
   - Sora for headings, one text face (Nivren Technical) for everything else. Both self-hosted woff2 Latin subsets.
   - Dark sections use .band--char (also the engineering-page variant). */
