   Corporate Design (Appearance) page: controls + the animated device preview.

   The preview is an ILLUSTRATION, not UI — everything lives under
   .mock-scope, which theme.css exempts from the radius/shadow mandate. All
   mock styling reads preview-local vars (--pv-*) set from the CURRENT
   (unsaved) selection, plus [data-pv-theme="ks"|"classic"] shape variants —
   fully independent of the app's live theme.
