Fix Nucleus render: EAGLE-rendered pcb.svg + schematic (was KiCad-only --render-board)
wire 3D: copy <slug>.glb -> render/board.glb so the wiki + Project Manager show the model
Set hero: hero-photo-v1.png
hero: molecule photo (3D viewer render)
re-anchored GLB (FL-pin fix)
Update with anchored GLB (MP markers detected)
