…slation - Errors caught by the error boundaries never reach window.onerror, so exception autocapture missed them. Both fallbacks now report the crash to PostHog, waiting up to 15 s for it to load and respecting an opt-out. - A first page load that asks for chunks a deploy removed fails before hydration, as an unhandled rejection, and leaves the page inert. It now reloads, at most once per page per tab in 10 minutes; a failure the guard blocks is reported. After the app has started, failed chunks (link preloads on hover) are left to Docusaurus. - Browser translation moves text nodes React owns, and React's next removeChild or insertBefore throws. A guard tolerates the moved node and logs a warning (the workaround from react/react#11538). translate="no" on the copyable commands, the agent picker and both framework pickers. - capturePostHogEvent and the crash reporter share one helper for calling PostHog (callPostHog), so the availability, opt-out and error rules live in one place.
