			<pre class="pr-body">On Skyler's iPhone 17, releases played sound over a black picture, and then showed "This browser can't play it here" with the video gone.

			Why: both players (`moods.html`'s `attachRelease` and the tiding page's `attach`) were meant to use Safari's own HLS on iOS ("iOS: the browser's own"). They checked `'MediaSource' in window \|\| 'ManagedMediaSource' in window`. iOS 17.1 added ManagedMediaSource, so iPhones started going through hls.js 1.7.3 instead. There, the combined Opus+AV1 buffer was refused: hls.js fell back to the sound alone, or failed with a media error, which removes the video.

			Change: only classic `MediaSource` sends a release to hls.js. An iPhone has none, so it gets `master.m3u8` natively, and Safari picks the rendition. iPads and desktop Safari have classic MediaSource and keep hls.js and its quality bar.

			Checked: in Chromium on production's tiding page, faking an iPhone (no `MediaSource`, a `ManagedMediaSource`, native HLS). As deployed now, the video element is removed. With this change, the video's `src` is `master.m3u8` and hls.js isn't used. Not checked on a real iPhone: Skyler, opening `master.m3u8` straight in Safari will show whether Safari's own player gives a picture. PickiPedia's Release page player has the same hls.js-first order and needs the same change if this works.

			Deploy: redeploy maybelle (magenta)
			Worked on by: magent, Skyler and Justin, in #uploads-and-embeds and #general</pre>
