Caption: Figure 3.

Zoomed-in 4.4 μm NIRCam image, with ALMA 217–219 GHz continuum (white contours) tracing the disk morphology and VLA 10 GHz continuum (blue contours) revealing extended emission along outflow cavities. Contours correspond to 5σ, 10σ, 20σ, and 100σ (ALMA) and 3σ, 5σ, 10σ, and 20σ (VLA), with σ as defined in Table E1. Note: the central region of GSS30-IRS3 is highly saturated, meaning there are no data in the white region.
