/* what: styles for the omnixscience.com bridge, mobile-first (designed at 390 px, then scaled up), in the omnixresearch.com look:
 * tokens from the live gate screen (omnix-gate/assets/gate.css), the light Omnix emails (omnix-emails/templates/emails) and the
 * child theme (Inter); sources per token in omnix/projects/tiktok-launch-2026-11/notes/2026-11-10_bridge_build.md. Background
 * (design pass 10 Nov): a pale lab-grey field with a slow light drift, the molecular lattice canvas drawn by site.js and a static
 * fine grain, all fixed behind the page (no layout shift); static when the visitor prefers reduced motion · system fonts, no
 * webfonts, no outside requests · owner: builder (omnix/patches/omnixscience-bridge-2026-11) · read when: changing the bridge
 * look · updated: 2026-11-10 (design pass: notes/2026-11-10_design_pass.md) */
