ImVec2	Consume (ImVec2 wheel, float dt, float step_px, float snap_px)

Public Attributes
ImVec2	residual {0.0f, 0.0f}

float	idle_seconds = 0.0f

Detailed Description

Turns wheel/trackpad deltas into pan steps that land on whole detents.

Pure state machine (no ImGui calls) so the feel is unit-testable. Input below the deadzone is ignored, direction reversals drop the residual, and the residual is discarded once input stops for kOverworldWheelIdleResetSec.
