v0.6.0 — an audio option, for a station that is HLS but has no picture
The audio shape was inferred from the source alone: an .mp3 got the compact bar and everything else got a 16:9 stage. A SiriusXM channel is an .m3u8 whose playlist carries nothing but AAC, and it was drawn as a black stage with a LIVE badge over a picture that never arrives.
Now: createPlayer takes audio: true, and infers it when the element passed as media is an <audio>. A caller that passes neither sees no change.
Full detail in #7. pnpm test: 119 pass, 0 fail.
