Hex Socket Unified GUI now reuses the shared BT3 textures to avoid duplicate assets:

textures/gui/bt3_native/panel4.png
textures/gui/bt3_native/btn2.png
textures/gui/bt3_native/btn1.png
textures/gui/bt3/button_normal.png
textures/gui/bt3/button_hover.png
textures/gui/bt3/button_selected.png
textures/gui/bt3_native/panel_512x252.png

Override those shared paths in a resource pack to restyle the unified picker.
