mow_heat

Heat shimmer over the FRESH CUT estate. Two layers of value noise scroll upward and offset the scene sample, so the air wobbles; the offset is scaled by smoothstep(14, 70, linear_depth), so the mower in the foreground stays crisp while the mansion, treeline and horizon cook. veil mixes the same distance mask toward a pale warm haze.

near_p/far_p linearize the depth sample and must match the scene camera's planes. game_t is the part clock, pushed each frame by preseed.parts.p_mow through postprocess.setProperty, so the wobble advances with the shot rather than with wall time.
