/* ============================================
   PDF EDITOR STYLES
   Theme-aware: buttons invert via --ink/--paper so they stay readable
   in light AND dark mode. The PDF pages themselves always stay white
   (they represent paper), so everything drawn ON a page uses fixed colours.
   No inline styles anywhere on the editor page - its strict
   Content-Security-Policy forbids them.
