iCalendar Timezone & Daylight Saving Best Practices

Always specify UTC timestamps or explicit timezone identifiers (TZID) to ensure event times do not shift when imported by attendees traveling across time zones.
Keep event descriptions concise to maintain high QR code scannability on printed paper invitations.
Event text uses the iCalendar VEVENT structure from IETF RFC 5545, simplified (no UID or timestamp fields); test-scan with the phones your guests use.
