/*
 * TangoTag site styles. Brand tokens come from tokens.css (a copy of
 * brand/tokens.css, the MGS Tango source; never edit tokens here).
 *
 * Legibility rules borrowed from TangoHive (Brent, 2026-08):
 * - Primary buttons are coal with white text, never coal on voltage.
 * - Secondary text is storm (#3F3F46), not muted grey, on white or cloud.
 * - Small green text is voltage-deep (#15803D); bright voltage is only for
 *   fills, the wordmark suffix on coal, and focus rings.
 * - Links are plasma-deep, bold, underlined.
