 * Altru.dev — Dichroic design system (public site)
 * Version 2.0.0 · replaces the legacy site.css on public pages.
 *
 * Layers, in order:
 *   1. Tokens          5. Header / footer      9.  Product & trust pages
 *   2. Base             6. Home                 10. Progress
 *   3. Primitives       7. Data components      11. Editorial pages (about, mission, lab, contact…)
 *   4. Layout           8. Catalog              12. Utilities, motion, responsive, print
 *
 * --sx (0–1) is set on :root by altru.js from pointer/scroll position. Every
 * dichroic surface reads it, so the colour bands shift together.
