per user-request einen branch der main-content UND rewrite-content trägt — saubere separierung statt symlink/merge-conflict. struktur: - slides/<course>/ → main-content restored, eigene assets (kein new-demo-leak) - slides/<course>-2026/ → rewrite-content, eigene assets (komplett kopiert + new demos) Makefile: COURSES += 223015b-2026 223015c-2026 dhbw-2026 mit eigenen NAME/KAPITEL/DEPLOY/KLAUSUR-konfig. Klausur für b+c=1, dhbw=leer. Deploy-paths /hdm/223015b-2026 etc. make build durchlaufen für alle 6 decks, 0 fehler. dedup: 223015c+dhbw assets identisch in beiden ordnern (kein neu-demos auf b ergänzt). 223015b 86 → 120 files in -2026 (= +34 neue eroeffner/usb-c-drei-achsen/container-vs-codec/etc).
