/* ─────────────────────────────────────────────────────────────────────────
 * aptpen.com site theme
 *
 * Design system:
 *   - Single dark background (#07090a) and acid-green accent (#7cff5b).
 *   - Monospace everywhere (JetBrains Mono / Fira Code, system mono fallbacks).
 *   - Hairline 1px borders against #1d272b panels, no shadows except the
 *     hero clock and CTA hover states.
 *   - 1440px content container, 64px horizontal padding on desktop.
 *
 * Class naming: BEM-style. .topbar, .topbar__nav, .topbar__nav-link.is-active
 *
 * Migration notes for whatever framework picks this up:
 *   - The CSS custom properties below are the only theme tokens.
 *   - All components are pure CSS — no JS interaction depends on a class
 *     except .form-chip.is-active (toggleable on click).
 *   - The interactive ATT&CK matrix on /methodology lives in
 *     /js/matrix.jsx and is the only place React shows up.
