/* Helix GTM Consulting design layer, B2 (run 11, 28 September 2026; owner decisions D6, D11, D12 in decisions-run11.md).
   ONE layer: it replaces the run 7 to run 10 helix.css (every old rule is listed in design/run11/css-changes.md) and folds in
   the rules main, hub and connector pages took from brand.css and app.css, so those pages load fonts.css and this file only.
   Reference: design/run11/helix-b2-home.html and helix-b2-inner.html. Brand: oxblood #641220, signal #C1121F, paper #FAF8F6,
   ink #1A0E10, clay #EAD9D5; added: muted #5A4B4E, white, rose #F6D4D8, rose-mid #F2AAB3, sky #CFE6F5.
   Fonts (self-hosted, fonts.css): Archivo (display and text), IBM Plex Mono (labels), VT323 (window bars and tags, 20 px or more).
   Dark mode follows the device setting only: one prefers-color-scheme block at the end swaps the tokens. */
