Fix mobile portrait video overflow + preserve YouTube title hiding

sizePW() rewritten: iframe height is always exactly vh so the top of the iframe
aligns with y=0. The YouTube title bar (shown briefly on play) falls within the
52px #tb overlay (z-index:5) and stays hidden.

Portrait (vw/vh < 16:9): w=vw, h=vh — YouTube letterboxes the 16:9 video
  internally; no horizontal overflow.
Landscape / ultrawide (vw/vh >= 16:9): h=vh, w=min(vw, vh×1.778) — no vertical
  cropping; side black bars from #pw background on very wide screens.

// Wider than 16:9 (landscape / ultrawide): constrain width to height × aspect ratio
// so the video is never taller than the screen (side black bars from #pw background).
// Narrower than 16:9 (portrait): fill the full viewport — YouTube letterboxes the 16:9
// video internally with black bars above and below the video content.
