/* ============================================================
   Demo — RFI Answer Pack Builder
   BPS-04 responder console inside the Asite CDE chrome.
   A real, preparation agent turns an open RFI into an answer pack:
   the question restated, the drawings / specs / prior RFIs gathered
   (each openable), a grounded draft response and the open points to
   confirm. It prepares; issuing the answer is the human's step.
   References + the RFI preview open via the shared U.sampleDoc.
   Selectors prefixed `rap-`. Builds on main.css.
