/* DaqFox — site.css
 * White page, one cool grey band, one navy band to close. Navy ink, steel accents.
 * Light only. Tokens first, then base, layout, components, pages.
 *
 * Type scale (use only these):  11 · 13 · 15 · 17 · 20 · 24 · h2 · h1
 * Breakpoints (use only these): 1020 (nav, hero) · 860 (splits stack) · 560 (phone)
 * Shadow: only the hero app window and the calculator.
