/* ============================================================
   Nascia — Studio

   Light, flat, no gradients. One stone-coloured ground, white
   panels with rounded corners, one green accent, and a single
   dark inset for the build log. Everything is sized in rem so
   Presentation mode (root 16px -> 20px) scales the Studio view.
   Device frames are the deliberate exception: they are in real
   CSS pixels so the generated app's responsive breakpoints fire.

   Two views share the page. html[data-view="landing"] shows the
   showcase (hero, video, gallery, "try your own idea") as full-height
   slides the page snaps between; html[data-view="studio"] shows the
   live build console.
