Treats the gate as a floor rather than a target — the suite runs well above it,
and a PR that legitimately trades a few points should not have to move the
numbers to land.
Pushes lines from 95.2% to 98.1% and branches from 85.2% to 89.9%, mostly
in the release-notes modal, the reservation overlay, the journey entry sheet
and the trip dialogs.
jsdom replaces globalThis.AbortController with its own implementation;
Node.js undici-based fetch validates signals via instanceof against the
native AbortSignal, causing fetch to throw before MSW could intercept.
Fix via custom Vitest environment (tests/environment/jsdom-native-abort.ts)
that captures native AbortController/AbortSignal before jsdom patches them
and restores them after jsdom setup.
Also updates JournalBody test 004 to match component behaviour (headings
rendered as <p>) and removes debug console.log statements.
