-- Module:DailyPriceTable
-- Generates a table of daily-updated product prices,
-- with each cell changing automatically once per day.
--
-- Features:
-- • Seeds randomness each day using localTime.year + localTime.yday
-- • No manual intervention required
-- • Tier prices derived from the final adjusted price
-- • Minor event-based price boost for special days
