- epub-gen.ts: reflowable (markdown → styled xhtml) and fixed-layout
(Typst per-page PNGs wrapped as pre-paginated EPUB3). No new deps.
- typst-compile.ts: compileDocumentToPages() rasterizes Typst directly
to PNG via the CLI (no poppler/mupdf needed).
- Persistent publications store at /data/rpubs-publications/{space}/{slug}
with public reader page, PDF + EPUB downloads at /{space}/rpubs/publications/{slug}.
- Preview/Press step now has quick EPUB download buttons next to PDF.
- Publish panel: "Publish to {space}" is now the primary action, showing
hosted URL + copy-link after publishing. EPUB variants remain in downloads.
- Dockerfile: new PUBS_DIR volume for persistence.
