/* CetusEd public site — shared design system (CP-R1528).
   Mirrors the platform/presentation design language: Sora + IBM Plex Mono,
   navy/teal palette, the five-lane focus colors, glass cards, the dual-wave field.
   Motion is gated behind prefers-reduced-motion (the site, unlike the deck,
   must respect the OS reduce-motion setting). No inline styles/scripts on pages —
   this stylesheet is the only styling source (CSP: script-src 'self').

   Watermark hero background replicates the app login overlay (MTSS2RTI.html
   _kgOverlay): linear-gradient(135deg,rgba(15,23,42,.86),rgba(30,58,95,.84)),
   CetusEdLogo.webp at 6vw center/auto 120% no-repeat, #0f172a.

   SCREENSHOT SNIPPETS (CP-R1547) — .shot
   Trimmed product surfaces used as evidence beside the claim they support.
   These are SUBSECTION snippets lifted from CETUS_PRESENTATION.html's live
   previews, not full screens: a claim about error types shows the error-type
   grid, not the whole kiosk.

   Every class is namespaced `sh-` and scoped under `.shot`, deliberately. The
   deck's originals use bare generic selectors (.nm .sup .ov .ev .k .v .sh .sv)
   that would collide with site classes the moment they were ported. The rules
   below use only tokens this stylesheet already defines, so dark mode needs no
   second implementation.
