/* styles.css — Editor chrome only.
   The page styling (1920x1080 frames, themes) lives in templates/_base/.
   This file styles the surrounding SPA: input form, grid view, modal, toolbar.

   Anything inside .editor-chrome must hide in `body.printing` and `@media print`
   so the export PDF only shows the page frames.
