   Virtual Hotelier template kit: vh-demos.css
   "App demos" overlay (.vad) + the phone mock-ups it shows: Before (.vdb, a
   desktop site scaled onto the phone) and After (.vdn, the single-property
   guest app = the "Mulgrave" template of docs/site-templates.md section 4).
   Ported from artifact/index.live.html <style id="vh-app-demos-css"> 281-393.
   Dropped on purpose: every .vda-* rule (dead code, P14) and the
   `html body .launch-tile[data-app-demos] .launch-icon` override (vh-core.js
   draws tile icons from VH.launcher.tiles[].icon instead).

   Scope: every selector here matches only elements vh-demos.js creates
   (.vad, .vdb-*, .vdn-*), so the host's desktop layout is untouched at any
   width; the overlay itself is not wrapped in the 640px media query because
   VHDemos.open() is also a desktop sales tool (deep link #app-demos).
   Colours: the overlay chrome reads --vad-* custom properties (defaults
   below = the Virtual Hotelier palette); VH.demos.theme or host CSS can
   override them. The gold accent falls back to --vh-accent from vh-core.
   --vh-hide is the hidden strip at the bottom of a frame (vh-landscape.js).
