The initial motivation is to trigger early dark energy (EDE) using the total fluid equation of state that encodes the cosmic radiation-matter transition, thereby addressing the associated coincidence problem. The EDE dynamics are analyzed in detail by recasting the background evolution equations as a two-dimensional dynamical system.
