One sticker on the table swaps between breakfast, lunch, dessert, and weekend brunch menus by the hour. No reprints when prices shift.
08:00–12:00 serves the breakfast PDF, 12:00–16:00 the lunch combos, 16:00–22:00 the dessert and evening-class menu. Weekends auto-flip to brunch. Pricing updates in the EQR panel take 5 seconds; the printed sticker never changes.
Free tier includes 1 standard QR code. Upgrade to the paid Eternal tier for blockchain permanence and the recovery key.
