/* Browser-chrome frame for the live preview. `.browser`/`.bbar`/`.url` in
   landing.css are scoped to `.hero-demo`, so the frame is styled here. It is
   intentionally theme-INDEPENDENT (always light): the form preview should read
   like a screenshot of the deployed form regardless of the marketing page theme.
   The embed renderer's `:host { all: initial }` wipes any background on the mount
   itself, so the light surface lives on `.tpl-preview-body` behind the transparent
   shadow host. */
