API returns naive date strings (e.g., 'YYYY-MM-DD') representing routine start and end dates. When parsed and formatted locally, negative UTC offset browser timezones shift the date backward by one day (e.g., formatting UTC midnight as the previous day in local browser time). To fix this, we: 1. Implemented 'formatNaiveDate' in 'date.ts' to format date strings and standard Date objects timezone-agnostically using 'timeZone: UTC'. 2. Replaced 'dateToLocale' calls with 'formatNaiveDate' in routine detail, template detail, and overview screens. 3. Added exhaustive unit test coverage in 'date.test.ts' verifying parsing, month boundaries, Date object support, and invalid/fallback inputs.
