specularConstant=0 wasn't producing a fully transparent specular layer in Chromium — it rendered as opaque-black-masked-to-text and got merged on top of the underlying paint colour, hiding the green fill of body.paint-green behind a black silhouette. The dark-paint default never revealed it because the underlying text was already near-black. Removed the upper-left feSpecularLighting / feComposite / feMergeNode from paintGloss and paintGlossHover. Visible look is unchanged (the contribution was already 0) and paint-variant background colours now read through correctly. paintGlossWhite/Btn variants untouched — their constants are non-zero, no black-mask risk.
