/*
 * Shared styles for the Bikn legal 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. It doesn't govern this site,
 * which is reference reading on a desktop or phone at rest, so dark mode is
 * honored here. The palette is neutral slate with the app's own primary blue
 * (#2E6BE6) as the single accent, so the two still read as one brand.
