/**
 * Print-CSS für kuratierte Katalog-Seiten.
 * Wird via flipbook.css am Ende geladen (separates File für Übersichtlichkeit).
 *
 * Strategie:
 * 1. `#kr-print-stage` ist nur im Print-Modus sichtbar
 * 2. `@page` setzt A4-Format + Margin = 0 (Padding macht das Layout selbst)
 * 3. Jede `.kr-print-sheet` bekommt `page-break-after` damit eine Page pro Blatt
 * 4. `.kr-printing` auf body versteckt die Live-UI während des Drucks
 */
