/* Paper. The round-2 design print sheet, class names matched to the site.
   Every page links this with media="print"; /set/{id}/checklist/ links it for all media so the screen
   view matches paper. The checklist's running header (set and ACN range) and footer (site + snapshot)
   are emitted per set by render.py as an inline @page rule. Paper size is left to the printer
   (Letter or A4); margins are in mm so both fit. */

/* Paper uses static Source Sans 3 and Source Serif 4 (Adobe's release instances, unmodified): Chrome writes variable fonts into
   PDFs as Type 3, which bloats long checklists. Fetched only for print (the checklist preloads them). */
