Both halves share the same pixel-lookup from the keymap. Left half maps correctly but right half's LED chain maps to left-half key positions (e.g. chain 6 → key 36 instead of key 39).

Works visually on symmetric layers (same color for left/right alphas) but shows wrong colors on asymmetric layers like HUB where left = BT/RGB controls and right = nav/symbols.

Needed: Per-half pixel-lookup — either via preprocessor conditional in keymap, separate overlay files, or automatic mirroring in the underglow-layer code based on split role.
