/* QPA Generator – styles
   Brand: Question Paper Alignment (navy #1b2440, gold #e0a63e, cream #f1ece1, Nunito)
   Note: printed-paper styles live in qpa.js (PAPER_CSS) because they are also written into the downloadable print file. */
/* Layout: QPA brand workbench — cream desk, navy ink, gold highlights.
   Desktop (>980px): navy summary on the left, form on the right; print controls beside a live A4 preview.
   Phones/tablets (≤980px): one column, a sticky bottom action bar carries the main action of each step,
   and the print step switches between "Paper details" and a preview scaled to the screen width. */
