Overview of stellar and wind parameters.

Name	Parameter	Value
Stellar luminosity	L_★	8 × 10⁵ L_⊙
Stellar mass	M_★	50 M_⊙
Stellar radius	R_★	20 R_⊙
Stellar wind temperature	^Twind	40000K
Eddington factor	Γ_e	0.42
CAK exponent	α	0.65
Line-strength normalisation		2000^(a)
Line–strength cut-off	Q_max
Thermal to sound speed ratio	v_th/a	0.28
Isothermal sound speed	a	23.3 km s^-1

Notes. ^(a)This parameter is varied throughout our models while keeping all others fixed. Specifically, we take values of = Q_max = 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, and 2000.
