Soldermask lines should appear UNDER plated holes/yellow copper

[seveibar]

May require a PR to circuit-to-svg

Ig it is due to the improper priority numbering in the pcb layer object sorting

mind if i take a shot at this?

The interactive 3D viewer had the same stacking: combined board textures painted soldermask after through-hole copper, so mask covered yellow annular rings.

Fix on the 3d-viewer texture path: tscircuit/3d-viewer#991

GLTF export still goes through circuit-to-svg (showSolderMask: true). Plated-hole groups there already sort on the through layer above top-layer soldermask overlays; if this screenshot was from the GLTF PNG path and still reproduces, the remaining work is SVG type/layer priority rather than 3d-viewer.
