Bug A: Center click to go back now works after switching months while drilled down. Fixed by saving root state BEFORE drilled state in selectMonth, so historyIndex=0 always points to root. Bug B: Unknown subcategories (not in December data) now get distinct colors. Fixed by tracking unknownCount separately and using (predefinedCount + unknownIndex) % 10 to assign colors starting after the predefined palette positions.
