TextureToolbox — drop PNGs here.
  Name.png            = replaces texture 'Name' in its main/albedo slot
  Name_Emissive.png   = replaces it in the emission slot
  ATLAS-Name.png      = rewrites the original texture IN PLACE
                        (atlas-safe: sprites/UI keep working)
Property suffixes: _MainTex _Albedo _BaseMap _BaseColor _Emissive
  _Emission _Normal _Bump _Metallic _Specular _Occlusion _AO
  _Height _Detail (dashes in names are fine — suffix read off the end)
Hotkey: F10 reloads this folder (rebindable in TextureToolbox.cfg)
