   tagger.css — minimal-theme styles for the embedded PoS tagger widget.
   Loaded only on the tagger's project page. Selectors match the IDs/classes
   that js/tagger/app.js binds to (and generates), so they must stay as-is.
   Uses the site design tokens from universal.css; adds the POS tag colours.
