/* Shared Beleg print geometry — the @page + paged.js-safe break rules used
   by BOTH the browser-print path (loaded via a media="print" <link> in
   app/layout.tsx) AND paged.js (passed to the Previewer in beleg-paged-preview.tsx).
   Keeping the @page + break rules in a single file makes the on-screen paged.js
   preview and the actual browser print break 1:1 by construction.

   IMPORTANT — this file does NOT host EITHER per-page footer mechanism. The two
   footer feeds are kept isolated, each in its own file:
     * NATIVE browser print → public/beleg-print-native.css (the display:table /
       table-footer-group running footer; loaded via a media="print" <link>).
     * paged.js screen preview → public/beleg-print-paged.css (the
       position:running(belegFooter) + @bottom-center running element; passed to
       the Previewer ALONGSIDE this file).
   This file carries NEITHER — it must stay safe for both feeds: the native
   display:table switch would collapse the paged.js preview to one page
   (Stefan-Bug 2026-06-08), and a paged.js running rule would be inert / wrong in
   native print. So both footer position rules live OUT of here. Everything in
   THIS file is safe for paged.js AND native print to apply.

   GoBD (Commit 1, supersedes the 2026-06-07 Schritt-0-Lock): break-inside:avoid now
   applies to ALL Belege (no festgeschrieben carve-out). The original scope assumed
   the browser's NATIVE break engine could diverge between a festgeschriebenes
   invoice's issue + its reprint, so it left festgeschriebene Belege on the browser's
   existing pagination. Under the deterministic paged.js chunker — which both the
   on-screen preview AND the standalone print route now use — the issue + reprint go
   through the identical pagination (the invoice reprints from its immutable snapshot
   through the SAME chunker), so „keep the issued page breaks" holds by construction
   and the carve-out is meaningless. All Belege get the clean break-inside:avoid. */

   Keeping both OUT of here keeps this shared geometry safe for both feeds. */

   holds by construction (the breaks ARE the paged.js breaks, both at issue and at

   native break engine could diverge between issue + reprint; it cannot under the
