/**
 * The timezone pass.
 *
 * Every CI runner is UTC, and a date bug that mixes a UTC calendar reading with a LOCAL one
 * agrees with itself in UTC — it only shows up somewhere else. `formatRelativeDate` shipped
 * exactly that and the whole suite stayed green, so "UTC" is not a neutral default here, it
 * is a blind spot.
 *
 * TZ has to be set before the process starts (V8 caches the zone on first use, so neither a
 * `process.env.TZ` assignment inside a test nor a custom testEnvironment can move it), which
 * is why this is a second invocation rather than a project inside the main config.
 *
 * Add a test here when its expected output depends on the viewer's calendar day.
