// page's manifest from E2E_SOURCE_PUBLIC_DIR while it holds one
// (playwright.config.ts, app/lib/source.ts). Each test writes it and removes
// it, so every other spec reads public/. The history PAGES themselves — what
// stagit rendered and the publish rewrote — are source.spec.ts's, over the
// checkout's real publish.
