coupled matter ↔ radiation ↔ surface · the 589 photons piling up in the trapped core · GPU compute + raymarch volume render
3-D Spatial Radiance Visualization · emission integration of pre-escaped radiance (g₀ baked in field) · blue-noise jitter · ERT

Field — cross-sections + radial profile
axial slice (x–y, mid-height) — looking down the cylinderside slice (x–z, through axis) — the column
radial profile: log₁₀(field) vs ρ — the soup gradient core→walllocal spectrum — intensity vs wavelength at the selected depth. The 589 core dip = self-reversal.
0 = core (deep soup) → 1 = wall skin
same, as a depth × wavelength heatmap (wall→core→wall): 589 broadens/reverses toward core; 819 stays peaked
