Diagnosis: no native video rendered at all (bg went black, but camera AND
screen tiles were empty). WKWebView does NOT composite native subviews placed
under its scrollView through transparent web content — only the webView's own
layer background shows through. So the video was effectively invisible.
Fix (the standard hole-punch): insert the video tiles into the WebView's
SUPERVIEW, BEHIND the (fully transparent) WebView, so the web content paints
on top and the video shows through. Changes:
- makeTileView / syncVideoTiles: insert belowSubview: host (the WebView) in
host.superview, and offset frames by the WebView's origin (getBoundingClientRect
is viewport-relative).
- webView.backgroundColor = .clear (was .black — a black webView bg would have
occluded the video behind it); the VC view's black background is the backing.
Plugin-only change — needs a Codemagic build. Web (transparent chain, zoom,
bz-hasvid) already correct.
