Prüfung aller 5 Beispielbücher über die Befehle der Buch-README (HTML,
EPUB, PDF mit weasyprint und xelatex):
- QA3-04: Der EPUB-Befehl der Buch-README hatte kein --mathml; im
Mathebuch blieben 1072 Formeln als TeX-Text. Jetzt 4904 als MathML.
- QA3-05: Kapitel-Startanker von epub2md_merge.py begannen mit einer
Ziffer (039-…). Pandocs EPUB-Writer löst Links darauf nicht auf (C-Buch
32, Mathebuch 20 tote Links). Jetzt kap-039-…; book.lua erkennt beide.
- QA3-06: portable_tex() passt Verlags-TeX für texmath an (\"u, \O,
@{…} und \arraycolsep in array, leeres \displaystyle vor Zellenende).
Mathebuch: 1 statt 9 nicht umsetzbare Formeln.
- Cover ohne Seitenzahl (print.css, book.lua).
Neue Tests: tests/test_pandoc.py (nur mit installiertem pandoc),
Parametertests für portable_tex. Andere Bücher byte-identisch.
