/* site.css — Quave shared design system.
   Structure and components follow the proven layout of other SenSym products (consistent
   site header/nav/footer, hero + promises grid, supporter pill, guide cards) while the SKIN
   stays Quave's own: planetarium dark, light/optics motif, amplitude bars as the hero.
   Used by every public page. textContent-only pages; this file is styling only. */
