// Miss #54 (2026-07-30): a `page.goto` fired while the previous heavy RSC
// navigation was still in flight aborted with `net::ERR_ABORTED`
// (campaignSavedFilters, prod build). `goto` stays legal for cold loads and
// URL contracts — the anti-pattern is two gotos with NOTHING between them
// that settles the first navigation. A settle is any awaited interaction
// with the landed page (assertion, fill, click, reload, login…): it proves
// the previous route rendered before the next one starts.
//
// Miss #53 (2026-07-30): the biometrics probe is one-shot per island mount,
// so a ceremony that starts before the CDP virtual authenticator answers
// never sees the enrollment UI. Specs registering a virtual authenticator
// must gate on `expectCampaignBiometricsReady` first.
