/* The free Game Model Builder pop-up on the course page (19 October 2026).
   A copy of the Game Model Builder page's newsletter pop-up (gmb-v2/nl-offer.css)
   with a "free with the course" tag on the cover and the reservation bar at the
   foot of this file. The original's notes follow.

   Newsletter offer pop-up. A native <dialog>, so focus trapping, Escape and
   the backdrop come from the browser.

   Revision 3, 11 October 2026: a navy panel holds the workbook cover, which
   settles in as the dialog opens. No prices anywhere in the pop-up, Lucas's
   ruling. Labels are plain text with a short rule, no pill boxes.

   Two columns from 720px, a bottom sheet with a navy band on phones.
   Brand tokens come from page.css, with fallbacks so it also stands alone. */
