v0.5.0

Minor Changes

• 2e51a9d: Add a scenes entry (@karnstack/kino/scenes): audio-driven React scene sequences.
  On the parent side, createScenesProvider and ScenesPlayer run scene iframes
  under kino's chrome; inside the iframe, createSceneHost and useSceneTimeline
  sync visuals to the audio clock over a postMessage wire protocol. Captions ship
  as sidecar VTT.
