Claude 1d8ca453c9 feat(teleprompter): anchor the read position and step between events
The scroll position was a pixel offset into a document that changes while
it is being read. Growing an event above the reader left scrollTop where it
was, so the text under the reading line slid: measured going from "Lucas
Bennett" to "Lunch" on an unchanged offset of 900.

Hold the position as a place in the script instead — the block under the
reading line plus an offset into it — and re-resolve it to pixels whenever
the document is measured. This follows how professional prompters cue a
story plus an offset rather than a scroll offset, so a reorder carries the
reader with the block and an edit above them changes nothing. A deleted
block falls back to the end of the nearest surviving event before it.

Add event-to-event stepping on Shift with the vertical arrows, matching
Shift being the coarser step on the horizontal ones, and take the step from
where the scroll is headed so pressing again mid-ease moves on rather than
re-aiming at the same event.

Free scrolling and the existing nudge and page keys are unchanged, but they
now hand over the scroll by one rule: how far the reader moved the script
themselves, accumulated. Distance from the follow target could not tell a
catch-up still running from a reader who had moved, so touching the wheel
while the prompter eased towards a newly loaded event stopped it following.
Accumulating also measures a wheel gesture the browser spreads over many
frames, which the old per-event check sampled only once.
