/* ==========================================================================
   ATHAR — creator.css

   The Artifact Creator: the workspace, the scene sidebar, the schema-driven
   content editor, the media library and the theme editor.

   The workspace is a three-column reading surface: scenes on the inline-start,
   the editor in the middle, and a live preview on the inline-end. The preview
   is a Player, so it is a reader and carries no editing controls.

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