Experimenting a little with @lfan’s System Bezel settings and I think I found the right settings, that will make the bezel stand out. I haven’t started @OrionsAngel’s stuff yet, for those wondering.
HSM_FRM_TEXTURE_OPACITY = "15.000000"
HSM_FRM_TEXTURE_BLEND_MODE = "1.000000"
HSM_FRM_SHADOW_OPACITY = "200.000000"
HSM_FRM_SHADOW_WIDTH = "60.000000"
