|
|
* Regression: `config.maxComboDepth` (DEFAULT_COMBO_CONFIG) had ZERO readers —
|
|
* nesting depth was always the hardcoded `MAX_COMBO_DEPTH = 3`, so the operator
|
|
* knob did nothing. This wires a clamped, per-resolution `maxDepth` through the
|
|
* combo depth functions (default preserved, hard-capped for safety).
