/*
 * Aphileon public site stylesheet — the "Atlas" theme.
 *
 * One shared shell for every public page (/ , /privacy, /terms, /coming-soon,
 * /shop-os/*, /apply/): a near-neutral palette, hairline rules, monospace
 * labels and small radii. Editorial rather than marketing: a sticky index rail
 * on long-form pages, product screenshots set as captioned plates, pricing set
 * as typography rather than cards.
 *
 * Deliberately dependency-free and hand-rolled — no build step, no framework.
 * Pages inline only what is unique to them; everything shared lives here.
 *
 * The mockup plates under /assets/panel-*.svg are illustrations of the owner
 * panel. That panel really is amber-accented, so the plates keep their colour;
 * the page chrome around them is neutral.
