nx_audio_render.nx

nx_audio_render.nx -- SOVEREIGN ZERO-JS audiobook player PAGE (rung 1 of SC33-37). Operator's correction: the player features are NISHI CODE, not browser JS -- the player BRAIN is a server-side Nishi audio daemon (nx_audio_serve, next rung) + our own DSP pre-rendering; the browser is a dumb NATIVE <audio> client. So "browser runs ZERO code" holds (same doctrine as the zero-JS text reader). This emits the static player HTML from reader/<slug>/audio.json: native <audio controls> (SC33 basic playback + the browsers' native speed menu) + chapters + the daemon-API affordances (speed-variant / sleep-timer / bookmark links+forms that target the Nishi daemon -- the "APIs" that do the work server-side). FAIL-CLOSED: scans its OWN bytes for <script and REFUSES to emit any (sovereign zero-JS, like nx_reader_render). Usage: nx_audio_render <slug>. expect_exit: 0 ORIGINAL
