The previous commit changed per-line reveal-duration distribution from ink-area to
word-count. That dropped a deliberate precision decision (area gives sub-line
granularity) and, verified live on a spanning paragraph, it was what made the
continuation page fail to animate. Restore area-weighting for the per-line split.
The word-share scaling of the *total* duration for partial (spanning) blocks and the
timeline-module timing snapshot/restore are kept — they only preserve existing
word-timings, they do not change the area-based per-line distribution.
Verified: on a real spanning block the right line reveals over its area share (~3.3s),
the page flips, and the continuation animates progressively across the next spread
over the full TTS (no fast-forward, no reveal-all-at-once).
