   EBKaC labs — Calendar printer
   Page chrome (hero, form panel, preview) + the printable sheets.
   Sheets are sized in mm for A4 landscape (297 × 210 mm); the
   on-screen preview scales them with `zoom` (set by calendar.js),
   print resets that so every sheet lands on exactly one page.
   Theme colours arrive as --t-* custom properties on #cal-pages.
