/* Z2PL shared stylesheet entry.
 * foundation.css preserves the pre-V3 base.css apart from the approved asset path move. It retains the original
 * reveal, visibility and responsive behavior. site-theme.css changes presentation only.
 * site-nav.js loads the canonical navigation stylesheet independently.
 * Page styles still load separately. The site theme uses html:root specificity deliberately
 * so later page styles cannot reintroduce the superseded dark/boxed sections.
 * Visual authority: docs/ui-research/v3-continuous-canvas.md.
 * Visibility update: docs/ui-research/v3-visibility.md (owner decision, 2026-09-25).
