   ============================================================
   Scoped stylesheet for the Function Task Brief template only.
   NOT linked from the wizard's index.html — the wizard uses
   style.css. The FTB intentionally departs from the wizard's
   app register and adopts a printed-business-document register:
   serif display (Literata) for headings, sans body (Figtree)
   for running text, generous margins, masthead, signature
   block, horizontal rule section dividers.

   The Pre-calibration vs During-calibration label distinction
   uses BOTH color (text-tertiary vs accent) AND typographic
   weight (roman vs italic) so the labels remain visually
   distinct in grayscale and black-and-white print.
