   ATHAR — player.css

   The Artifact Player. Everything in this file is scoped under `.art-*` so it
   can never reach into the application's own design system, and it reads its
   colours from the `--art-*` variables `themes.js` applies from the
   Artifact's own theme. The defaults below are the same warm-paper default
   the theme system produces, so an Artifact with no theme still renders.

   Only logical properties are used, so RTL is a single `dir` swap.
