/*
 * CoatMentor — shared design system (theme.css)
 *
 * Single source of truth for design tokens + core components. Loaded by both
 * index.html (landing) and app.html (members). Page-specific layout stays in
 * each page's own <style> block.
 *
 * IMPORTANT: class and id names here are also bound by the quiz/mock engine in
 * index.html and app.html (.opt/.sel/.correct/.wrong, .btn-primary, etc.).
 * Restyle freely, but do NOT rename these — the JS depends on them.
 *
 * Type note: display face is Sora (SIL OFL), SELF-HOSTED from /fonts — no
 * third-party origin, consistent with the site's privacy-friendly positioning.
 * Body copy stays on the system stack (fast, familiar). Headings, stats,
 * prices and the wordmark pick up Sora via --font-display.
