/* ==========================================================================
   CometX — reports, library and registration
   --------------------------------------------------------------------------
   Extends assets/css/site.css. It redefines nothing that site.css owns and
   inherits every token from it (--ink, --paper, --line, --b-lime …), so a
   palette change there propagates here automatically.

   Everything under `.rpt` is a sealed scope for the published report bodies.
   Those documents ship their own .card, .btn, .nav, .tag and .table classes
   that mean different things from the site's, so they are namespaced rather
   than merged: site.css cannot reach in, and the documents cannot leak out.
