config/filament-recurrence.php
timezone is the default used for new recurrence records and for data that doesn’t have a stored timezone. Each record can override it with the form field’s Timezone select — the chosen identifier (e.g. Europe/Berlin) is persisted in the recurrence JSON alongside the other fields. Hide that select entirely with RecurrenceField::make('recurrence')->showTimezone(false), which forces every record to use the config value.
