Summary

• @be-music/app-play 0.9.0: an AUTO checkbox switches the embed between the AUTO preview and the viewer's play without ?mode=; the lanes reach down to just above the seek bar without running under it (SP and DP, either orientation); a phone or tablet waits for a Load button showing the archive's size before downloading (Embed: AUTO checkbox, lanes down to the seek bar, and Load before downloading on a phone #875).
• @be-music/player-ui 0.5.0: autoPlay / auto-play-change on the preview list and start screens, load mode and caption on be-music-preview-start, previewJudgementInset and PREVIEW_CONTROLS_CSS_HEIGHT, and the HUD's controls along the bottom of the screen (Embed: AUTO checkbox, lanes down to the seek bar, and Load before downloading on a phone #875).
• @be-music/worker-play 0.1.3 / 0.1.4: /__url-load-proxy lets the browser revalidate a proxied archive (no-cache, ETag / Last-Modified, conditional requests) so an unchanged one is not downloaded again (Cache proxied embed tracks until the archive changes #873), and answers HEAD with the archive's Content-Length (Embed: AUTO checkbox, lanes down to the seek bar, and Load before downloading on a phone #875).
• Dependants bumped: @be-music/player-browser 0.13.2, @be-music/player-ui-react / player-ui-vue 0.2.3.
• Test-only: the embed play-mode spec's Pause locator (Fix the embed play-mode e2e spec's ambiguous Pause locator #869).
