	5	// Discovers every region file in src/data/calendars/ (except the SCHEMA doc) and
	6	// shoots each one, reusing a single dev server + browser. Output mirrors the
	7	// single-file script: screenshots/calendars/<file>/. Run this after adding or
	8	// editing calendar data so the checked-in screenshots stay current.
