   - **Quirks (2026-07-17):** `fb2+zip` format actually returns a ZIP (unpack: 1 fb2 + cover inside); `/b/<id>/pdf` sometimes 302-redirects to the book HTML page (a ~20 KB stub) when the file isn't served directly — check downloaded «pdf»s with `file`, fall back to libgen (same editions usually there) or the fb2 twin.
+- **Converter quirk (2026-07-18):** `/b/<id>/epub` (or any fmt endpoint) on a book whose NATIVE format is pdf/djvu/doc may return the **native file, not an epub** — always magic-byte-check downloads (`file`); some «20 KB HTML stubs» are in fact real native files with the wrong extension.
