 # EPUB3 -> PDF converter (Flask + WeasyPrint) — Coolify / any Docker host
 # WeasyPrint needs pango + fontconfig system libraries; CJK fonts for full-text support.
+# Rich mode: the Office trio (.docx/.odt/.rtf) renders through LibreOffice headless.
+# libreoffice-writer covers all three and provides /usr/bin/libreoffice; its dependency
+# pulls in the core soffice engine. Installed lean via --no-install-recommends.
