FrameLerp.Smooth is the framerate-independent smoothing path -- a Umbra-style v += (target - v) * factor with the factor clamped to 1 so a stalled frame snaps cleanly instead of overshooting. Tab gets two NonSerialized fields (_hoverAlpha, _cardHoverAlpha) that the v1.5.4 render loops drive.

// clamp is a deliberate HellionChat addition -- on Wine/DXVK a
|
|
// stalled frame can push deltaTime well over 16ms, which would
|
|
// otherwise let the raw factor exceed 1.0 and overshoot the target.
|
|
// Clamping makes a stalled frame land exactly on target instead.
