stocks of crude oil and petroleum products by PADD). Cushing is reported separately as
part of PADD 2 (EIA series W_EPC0_SAX_YCUOK_MBBL). Per-PADD shares and working capacities
are seeded from typical recent allocations until per-PADD weekly series are wired into
update_data.py. Tank-farm working capacity ≠ shell capacity; usable storage is the
relevant denominator.
