/* ============================================================
   Brochure-format PDF export for case study articles.
   Linked with media="print", so zero effect on screen.

   Page 1   full-bleed cover
   Page 2+  body: numbered sections, bleed figures, spec panel
   Close    sign-off and colophon
   Running footer repeated on every page after the cover.

   Deliberate robustness decision:
   Chrome's "Background graphics" option defaults to OFF, which
   drops every CSS background. So the cover's dark ground is baked
   into cover.webp as a real image rather than painted in CSS, and
   nothing anywhere depends on a background fill for legibility.
   Turning the option on adds refinement; leaving it off still
   produces a correct document.
