/*
 * FactureCheck brand tokens + the "compliance stamp" component.
 * Loaded on every site/ page, on top of Pico (CDN) which still owns
 * layout/grid/forms — this file only sets tokens, type, the stamp, and
 * a11y baseline. No build step: plain CSS, no preprocessor.
 *
 * Typography: this repo has no webfont pipeline (no /fonts, no @font-face
 * anywhere), so both faces are system stacks, not custom webfonts.
 *   --font-display: "Arial Black" first -- a real, widely-installed system
 *   face (Windows, macOS, most Linux via metric-compatible substitutes)
 *   that is genuinely heavier/blockier than default UI sans, giving the
 *   hero/section titles character without a serif (avoids the "cream +
 *   serif + terracotta" AI-look) or a webfont dependency.
 *   --font-body: the standard system UI sans stack -- calm, gets out of
 *   the way of --font-display.
 *   --font-mono: system monospace stack, used ONLY where mono carries
 *   meaning (rule_id, XML/SHA), never as a stylistic flourish.
