/* ==================================================================
   Threshold - file responsibility (th-resp-*)
   ------------------------------------------------------------------
   The Applicant File's owning block as a button and its non-modal
   Responsibility drawer, lifted from the approved Teams, routing,
   ownership and My Work canon (File Responsibility.dc.html; the
   handoff's drawer, radio-list and "What changes" primitives in
   handoff/threshold-ops.css). Values are the prototype's, on
   production tokens:

     --sunk -> --th-paper-sunk     --paper -> --th-paper
     --mono / --serif / --sans -> --th-font-mono / serif / sans

   No token is declared here and every colour tracks a theme token, so
   dark mode needs no override. Buttons, pills, banners, radio lists,
   fields, the textarea and the feedback notice are the shared atoms
   (cc-btn, cc-pill, th-banner, th-radiolist, th-radio, th-textarea,
   th-fb) and are not redefined. The owning block keeps All Files'
   lifted placement (.af-file-owning in all-files.css) and turns the
   static stack into the canon's button.
