/* ============================================================
 * Brighton International School — Redesign Concepts CSS
 * Three visual concepts sharing one stylesheet, differentiated
 * via body class: .c1 (Classic Warmth), .c2 (Modern Editorial),
 * .c3 (Bold Contemporary).
 *
 * Palette sourced from the real Brighton brand colors (as used in
 * mx_parent_pwa/static/src/pwa/app.css — logo shield oxblood +
 * crimson linework + logo gold), not an invented set.
 *
 * WCAG AA contrast verified for all text uses:
 * - Dark gold #786117 (darkened brand gold) on warm paper #faf8f8 → ~5.6:1 (pass)
 * - Crimson #c41e33 on warm paper #faf8f8 → passes AA for large/bold text
 * - Oxblood #4f1720 on warm paper #faf8f8 → passes AA
 * - Warm paper #faf8f8 on oxblood-dark #360f16 → passes AA
 * - Brand gold #c9a227 on oxblood-dark #360f16 → passes AA (dark bg only;
 *   fails on light backgrounds, so --gold-text uses the darkened variant)
 * ============================================================ */

/* ── Focus visibility (WCAG 2.4.7 / 1.4.11) ───────────────────
 * Every interactive element gets a clear focus ring on keyboard
 * navigation. Uses :focus-visible so mouse clicks don't show it.
 *
 * Double-ring technique (white ring + oxblood ring): a single
 * gold ring fails the 3:1 non-text contrast minimum against our
 * own light backgrounds (paper/white ≈ 2.3:1), so instead we pair
 * a white inner ring (contrasts against dark sections/buttons)
 * with a dark oxblood outer ring (contrasts against light
 * sections) — together at least one ring always reaches 3:1
 * against whatever the element sits on.
