/*
 * Shared styles for the Bikn public site.
 *
 * Scope note: CLAUDE.md's "light background only, never dark mode" rule is a
 * product decision about the crisis app — older, low-vision, and panicked
 * users read dark-on-light better mid-incident. This site is marketing/legal
 * reading, not the crisis flow, and product direction (2026-08-25) is a
 * deliberate dark-tech identity here: a single committed midnight-blue palette,
 * not a light default with a dark media-query fallback. It stays a considered
 * choice rather than an inversion-for-its-own-sake — every token below is
 * picked, not auto-flipped, and the app's own primary blue hue is kept
 * recognizable, just brightened for contrast against the dark ground.
