   Studio — the owner's workspace.

   Sized for comfort rather than density: 17px base text, 48px minimum
   button height, generous spacing. Someone should be able to use this
   on a laptop screen without leaning in.

   Uses its own --ui-* palette. The gallery's theme variables (--bg,
   --ink, …) apply only to the preview pane, so setting the website to
   a dark theme never makes these controls unreadable.
