Close-up maps (r ≤ 6M) in (r, θ) coordinates (with θ limited to the Level-3 SMR domain) of the same parameters as in Fig. 3 (from left to right) for the prograde a = 0.9 case at two epochs: t = 19 594M (upper row of panels) and t = 19 630M (lower row of panels). Each panel shows a slice for the azimuth ϕ indicated in its title (also marked in Fig. 5). The gray dashed circles mark the ergosphere boundary r_E(θ), the black dashed lines mark the boundary of domain magnetically disconnected from the BH horizon, the green dashed lines mark equipartition between magnetic and plasma enthalpies (σ = b²/w = 1), and the magenta contours mark the relativistic temperature log₁₀T = 0.5.
