about

nx_fb2_book.nx -- SOVEREIGN FB2 (FictionBook 2.0) -> Nishi format. The Nishi equivalent of Calibre's FB2 input plugin (OSS = benchmark, NOT a dependency -- per the sovereignty law). FB2 is a SINGLE XML file: <FictionBook><description><title-info><book-title>T</book-title> <author><first-name>F</first-name><last-name>L</last-name></author></title-info></description> <body> <section><title>..</title><p>..</p>..</section> .. </body></FictionBook> Extract title/author from <description>, run nx_html_to_text over the <body> only (FB2's <p>/<emphasis> are HTML-ish; unknown tags strip cleanly leaving the prose), emit the SAME book.json the zero-JS reader renders. Rung 1: whole <body> -> one chapter (readable); <section> chapter-splitting + <binary> images = next rungs. Usage: nx_fb2_book <fb2-path> <slug>. expect_exit: 0 license_tier: ORIGINAL
