Caption: Figure 4.

Magnetic field inclination in the network region at two representative photospheric depths. Top left: inclination γ at ﹩\mathrm{log}\tau =0﹩. Top right: inclination at ﹩\mathrm{log}\tau =-2.5﹩. Black circles mark locations exhibiting three-lobed Stokes V profiles in the Fe I 8468 Å line, where the inferred polarity reverses between the two layers. Labels 1–6 correspond to the profile examples shown in the lower panels. The gold star marks a distinct location where the observed Stokes profiles show opposite polarity between the photospheric Fe and chromospheric Ca lines, shown in Figure 6. Bottom panels: example Stokes V profiles from the locations marked 1–6, illustrating the range of three-lobed morphologies observed at the network boundary. The shaded regions show the 5σ noise level.
