/*
 * File:        docs/marketing/web/styles.css
 * Purpose:     Stylesheet for the static HTML/CSS reference implementation
 *              of Homepage v2. This is the visual ground truth for the
 *              Angular team's Phase 1 implementation.
 *
 *              Every token resolves to a CSS custom property. Every
 *              component honors design-governance-v1.md. The page
 *              should pass Lighthouse Accessibility + Best Practices
 *              before the Angular team adds the SSR layer.
 *
 * Spec:        docs/marketing/homepage-spec-v2.md (canonical)
 * Companion:   docs/marketing/design-system-v2.md (component definitions)
 *              docs/marketing/design-governance-v1.md (discipline rules)
 *              docs/marketing/assets/brand/brand-tokens.css (token source)
 * Version:     v1 (Phase 1.5 reference)
 * Date:        2026-05-26
 *
 * Organization:
 *   1. Brand tokens (synced from brand-tokens.css)
 *   2. Reset / base
 *   3. Typography utilities
 *   4. Layout primitives (container, section)
 *   5. Mode aliases ([data-mode])
 *   6. Components (button, nav, cards, metric strip, etc.)
 *   7. Section-specific layouts
 *   8. Responsive breakpoints
 *   9. Reduced motion + focus-visible (a11y)
