I Asked Polymarket for 90 Days of Prices and Got 30. Coarser Points Got Me 462

Polymarket's price-history endpoint caps the window by the bucket size, not by the dates you send. One parameter silently overrode the other in my own Actor, so a 90-day request came back as 30 days — and the fix was to ask for the market's whole life and throw most of it away.
