   SHARED EDITOR ENGINE STYLES
   Used by both index.html and tools/photo-signature-resizer.html
   so the interactive resizer panel looks/behaves identically
   wherever it's embedded. Relies on the :root custom properties
   (--ink, --accent, --surface2, --green, --red, --amber, etc.)
   already defined on the host page — keep those in sync if you
   add new ones here.
