# Unified 30-class label space for the combined puzzle-perception segmentation
# dataset. Class ids 0..29 are the values found in every mask PNG under data/.
#
# Source-task offsets:
#     maze   →  0   ( 8 classes,  ids  0.. 7)
#     chess  →  8   (15 classes,  ids  8..22)
#     hanoi  → 23   ( 7 classes,  ids 23..29)
#
# `weight_ce`   — per-class cross-entropy weight (handles class imbalance).
# `weight_miou` — per-class weighting for mIoU evaluation.
# Both are inherited from the per-task definitions in the source datasets.
#
# `background` appears twice (chess id 8 and hanoi id 23). The two are distinct
# classes in this unified namespace because they originate from different
# source tasks.
