   OpZone - landing page (Field Manual design system)
   Role: the FIELD MANUAL light-theme design system for HomeNew.razor and the
         site shell (tokens, header, buttons, section chrome, hero, ticker, the
         nine landing sections, footer, responsive rules).
   Load position: 8 of 8 in the website opz-*.css chain.
   Derived from app.css (2026-10-12 Field Manual round) - lane 6a renamed
         the landing-only classes to the opz- prefix.
   Derivation note: bare aliases remain only where MainLayout still references
         them (.header, .container, .nav, .footer, .brand, .menu-btn, .skip,
         .grain, .sr-only, .mono, .rule). Cross-app base classes
         (.opz-display, .opz-lede, .opz-reg) are canonical in
         _content/OpZone.UI/opzone-ui.css.
