/* Shared landing-page stylesheet — Phase 1 architecture refactor, 2026-07-29.
 *
 * ONE file serves both dusklight.app and hivespace.org. Every color, gradient,
 * and alpha lives in each page's own :root block (index.html <style>) — this
 * file only ever references var(--token). Editing structure/layout here changes
 * both sites at once; editing a :root block changes one brand.
 *
 * Source of truth lives at local/landing/shared/landing.css; deploy_landing.sh
 * copies it into each product's web root as landing.css. Values were lifted
 * verbatim from the pre-refactor inline styles — Phase 1's contract is that the
 * rendered pages are pixel-identical to before.
