despill pulls foreground chroma along the background-hue axis with no
positional or semantic guard, so a subject sharing the background's hue
(e.g. a blue suit on a blue backdrop) is desaturated and hue-shifted
(measured ~ΔE 35, blue -> purple) — a false positive on correct colours.
Flip the DespillSettings.enabled dataclass default to False so every lane
that omits a despill section — notably cpu-fast — inherits it off, and
mirror it in default.yaml. Re-enable per-config or with --despill when
edge spill genuinely matters.
