/* FLUXION Sprint Desk (10-14 demo). A lead desk, not a chat bubble:
   blue pixel-mosaic header, a paper sheet that slides over it, a transcript,
   a brief that fills in as you answer, and a bar meter that shows how close the plan is.
   Grammar: flat brand blue + dot screen, square corners, ink for action, blue only as signal. */
