/* ============================================================================
   Rules — V0-faithful port of app/rules/page.tsx.

   Structure: glass panel (gold border, top shimmer, 4 corner ornaments) +
   centered header (gavel icon → "GAME RULES" gold-gradient title with
   horizontal-line backdrop → "Nexian — Official Server Rules" subtitle) +
   Shield divider + intro-warning panel + scroll-activated rules list.

   The rules-list items themselves are rendered by render_scroll_section()
   so their dim → highlight behavior is in scroll-section.css. This file
   only owns the OUTER chrome.
