/*
 * FCRO brand usage guide (ticket #146)
 * Charcoal      #1C1C1E — authority, clarity: headings, ink, dark hero/panel backgrounds
 * Electric Blue #1F6FEB — trust, competence: primary buttons, links, icons, nav, diagrams, hero accents
 * Crimson       #C1272D — energy, action: CTA band, primary-button hover, urgent highlights (used with intent, not decoration)
 * Gold          #D9A441 — premium value: key stat numbers and numbered markers only, used sparingly
 * Soft White / Graphite Grey / Mist Grey — neutrals: backgrounds, body text, section dividers
 * --blue-ink is a darkened Electric Blue kept at ~5.9:1 contrast for small text on light backgrounds;
 * --blue-tint is a lightened Electric Blue for text/accents on dark backgrounds (hero, panels).
