   Skyscape preview cluster — shared stylesheet
   /preview/assets/preview.css

   Serves /preview/ (home) and /preview/about/.

   PREVIEW system, deliberately separate from /brand/skyscape.css so
   experiments here cannot destabilize the live RHTP cluster. Once the
   direction settles, fold the durable parts into the brand stylesheet and
   retire this file.

   2026-10-08: display face switched Roboto Slab 300 -> Rajdhani 600 per
   brand decision (matches the Buzz app typeface). /brand/skyscape.css v4
   still carries Roboto Slab — fold in once the preview direction settles.

   2026-10-13: backdrop-filter REMOVED sitewide. With every animation frozen
   the page still flickered and hairline borders dropped out after first
   paint — both are compositor artifacts of stacking seven blurred surfaces
   (nav, three hero panels, two doors). "Glass" is now a solid translucent
   fill: same look at arm's length, zero per-frame cost. Do not reintroduce
   backdrop-filter on this cluster.

   2026-10-13 (2): card outlines strengthened. --mist at #E4EDF3 sat at
   ~1.07:1 against white — effectively invisible on many displays. Token
   darkened a step, and the three card families (then/now, phases, quotes)
   carry an explicit ink-alpha border that survives zoom and subpixel
   rounding.

   2026-10-14: MOBILE NAV DISCLOSURE added (bottom of this file). The pages
   on this stylesheet previously had NO menu at all below 900px — navmid
   was display:none with nothing replacing it. Now a checkbox burger, the
   same no-JS pattern the knowledge page uses (preview-system.css §8a).

     - an optional .m-only item inside .navmid (e.g. Book a demo), hidden on

   The checkbox stays visually hidden rather than display:none so the menu
   keeps keyboard and tab access.
