API reference: `roundsOk` carries `null` for a run still going, a
background command's `output`, script writes in `edits`, what `helpers`
counts, and the page text budget behind `truncated`.
src/web/CLAUDE.md: panels kept by identity, the balloon text span the
clamp must target, the drawer's unchanged-refresh skip and held turn, the
drawer under the bar and the inert page behind a full-width one, and text
tokens versus accents.
