What

Transcript scroll and seek handlers, the global-state subscriber and the sticky-prompt context moved off ref-held callbacks onto React's effect-event hook, and a self-rescheduling timer helper replaced the old interval utility, including the 30-minute update check. This removes stale-closure and overlapping-run hazards.

Evidence

useEffectEvent

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
