The sing beat, and a page a phone can actually use

[codewithwan]

Two bugs, both found by using the thing rather than by any test I'd written.

The lyrics never appeared

rasterize picks the karaoke line or the caption strip, never both — and
the karaoke line is half the size and sits up at his shoulder, not under the
ground. The preview drew the song's intro, in the caption strip, at caption
size, forever. So the three lines somebody had just typed were never once on
screen.

Ported properly: same scale, same place, same 30-tick cycle, and the strip
stays empty like it does in the file. Checked against a real render:

tick	lyric band	caption strip
560	1364 px	0	✓
600	2020 px	0	✓ (a different line — it cycles)
640	0	2808 px	✓ (past the beat)

Identical, both bands, all four ticks.

Drag did nothing on a phone

A finger starting on the handle can't be told apart from a scroll until it has
already moved — and by then the page has gone, so the gesture never reached
dnd-kit. touch-action: none on the handle, plus a touch sensor that waits
180ms: hold then drag, move first and it scrolls, which is what a finger on a
long page usually wants. The handle got bigger too; 8px of tap target is a joke
on glass.

Keyboard sensor while I was in there. A list you can only reorder by dragging
is a list some people can't reorder.

And the page was 15px wider than the phone

Grid and flex children are min-width: auto, so they refuse to shrink below
their content — and the canvas carries an intrinsic 1056px however hard
w-full argues. min-w-0 where it matters. Zero overflow on all three steps
now, measured, not eyeballed.
