   Paperwork — PDF Tool · themed styles
   Reuses global tokens from /assets/css/main.css (:root variables).
   All selectors are scoped under .pdt so the tool's generic class
   names (.panel, .field, .status, .btn-primary…) never clash with
   the rest of the site. Structural class/id names are preserved
   because paperwork-pdf-tool.js depends on them.
