/* site.css — the entry site's own layout sheet.
 *
 * Every brand-carrying value — color, radius, font, easing, the red press
 * signal — resolves through the design-system bundle's marketing token
 * layer (colors_and_type.css, linked beside this sheet): --basalt-*,
 * --circuit-*, --accent-*, --text-*, --pastel-gold, --border, --radius*,
 * --font-*, --liquid-ease. The bundle's token header scopes --app-* to
 * Canvas product chrome; marketing surfaces use this layer. The remaining
 * literals are layout geometry (widths, paddings, blur radii) and neutral
 * shadow overlays (pure black/white alpha, no hue) — never a brand value.
 * Visual foundations follow the bundle README: layered basalt background +
 * grain, glass surfaces, two co-leading brand colors, red press signal,
 * no emoji, reduced-motion honored. */
