/**
 * Page-specific styles for xdimaging.com marketing pages (Task T08) — hero, "how it works" steps,
 * "why xdimaging" tiles, capability sections, and generic prose pages (About/Contact/legal).
 * Chrome-only styles (header/nav/footer, resets, buttons) live in assets/css/base.css instead.
 * Same rule as base.css: only var(--...) for colors/fonts/spacing — no hardcoded hex/px-literal
 * color or font-family values (grep for hex codes: none should be found here).
 *
 * Breakpoint reference (matches base.css — not tokens, custom properties don't work in @media):
