/*
 * ATROTON Compliance page — standalone stylesheet
 * ================================================
 *
 * Loaded alongside /scanline.css and /ticker.css by /compliance.html.
 *
 * Design target: Gotham / Palantir Foundry / Linear docs. Restrained.
 * Dark surface matches the landing page. Typography uses the same
 * clamp() fluid scale that shipped on landing (PR #5).
 *
 * Standards referenced in this stylesheet:
 *   - WCAG 2.2 SC 1.4.3 / 1.4.11 — contrast ≥ 4.5 on body, ≥ 3 on UI.
 *   - WCAG 2.2 SC 1.4.12 — text spacing (line-height ≥ 1.5 body).
 *   - WCAG 2.2 SC 2.4.7 — focus visible.
 *   - WCAG 2.2 SC 2.5.5 / 2.5.8 — touch targets ≥ 24×24 CSS px, input ≥ 44 px.
 *   - WCAG 2.2 SC 1.4.10 — reflow at 320 CSS px without horizontal scroll.
