 * Locales that follow ISO 8601 week rules — Monday is the first day of week
 * AND week 1 contains at least 4 days of the new year (`minimalDays = 4`).
 *
 * Audited against `Intl.Locale#weekInfo` (CLDR). Entries previously listed
 * here that disagree with CLDR were removed:
 *  - `pt-pt`, `pt`  → Sunday-first per CLDR (was emitting wrong week
 *    boundaries for Portuguese)
 *  - `he-il`, `he`  → Sunday-first per CLDR
 *  - `ar-sa`, `ar`  → Sunday-first / Saturday-first per CLDR
 *  - `en-au`, `en-nz` → Monday-first BUT minimalDays=1, NOT ISO
 *  - `ro-ro`, `ro`, `sl-si`, `sl`, `hr-hr`, `hr`, `tr-tr`, `tr`,
 *    `uk-ua`, `uk`, `lv-lv`, `lv` → Monday-first BUT minimalDays=1
 *
 * The Temporal adapter consumes `Intl.Locale#weekInfo` directly (see
 * `usesISOWeekRules` in calendarMethodsTemporal). The dayjs/moment
 * adapters still use this static set; the removals above also fix
 * silent format/getWeek divergences in those adapters for the affected
 * locales when CLDR data is the desired source of truth.
