/* ═══════════════════════════════════════════════════════════════════════════
   pdf-inject — self-contained styles.

   The palette and the frame component are duplicated from the site's style.css
   rather than imported. That is deliberate: this tool is meant to be liftable
   into its own public repository, and a shared stylesheet would be the one
   thread holding it here. Nothing in this file leaks out, because nothing else
   loads it — and when the site's palette changes, this block changes with it
   by hand.
