   Add Text to Image - editor styles

   built on the template's own tokens (--bg-panel, --card-border, --accent-cyan,
   --accent-violet, --text-main, --text-muted) so the editor follows the page theme
   instead of hard-coding a second palette.

   Not preloaded: a face is only fetched when someone picks it. add-text-studio.js
   awaits document.fonts.load() before drawing, so the canvas never renders a
