/* ===========================================================================
   TEXT DIFFERENCE ENGINE  (/text-compare)

   Instrument aesthetic: grey ground under a ruled grid, white panels,
   hairlines, mono labels in wide caps, one blue for interaction.
   Colour is spent only where it means something — inside the diff.

   PORTING NOTE
   Everything is scoped under .tdx-page. The original design was a standalone
   document and styled bare `*`, `body`, `button`, `textarea`, `h1`, `del` and
   `ins` selectors — unscoped, those would have reset margins and restyled
   controls across the entire site. The variables moved from :root onto the
   page root for the same reason.
