/* CarrNET design system, web implementation (v0.2).
 *
 * Source of truth: ~/Documents/CarrNET/Design System/ (tokens, web components).
 * Ported here: the web display type scale, the radius scale, the shadow scale
 * (soft shadows replace flat borders on web surfaces), pill buttons with the
 * signal gradient, the dark glow hero, stats band, floating cards, gradient CTA
 * band and dark footer.
 *
 * Deliberate deviations, all for WCAG AA text contrast:
 *   --signal       #0C8599 stays for decoration (rules, glow, focus).
 *   --signal-text  is a slightly deeper teal for small text and links, because
 *                  #0C8599 on white measures about 4.3:1.
 *   --grad-start   #0A7A8D replaces #0C8599 as the start of the button and band
 *                  gradient so white text on it clears 4.5:1. The end colour is
 *                  the system's --signal-deep #075E6B.
 *   --muted        is deeper than #8A93A3 (about 3.2:1 on white).
 * The system defines no dark web theme, so the dark palette comes from
 * ~/.config/theme/palettes/carrnet.sh, and dark surfaces use a hairline border
 * instead of a shadow (shadows do not read on dark).
 *
 * No inline styles anywhere on this site: the CSP is `style-src 'self'`.
 * Keep every rule in this file.
