Contributed to the w3c/csswg-drafts repository by enhancing the CSS Color 4 rendering pipeline, focusing on numerical stability and color fidelity. Addressed a numerical instability in ray tracing by implementing an epsilon-based intersection check using JavaScript and numerical methods, which improved robustness for small rays and reduced edge-case failures. Developed and integrated color rendering gamut mapping enhancements, increasing tolerance in ray-trace mapping and improving handling of out-of-gamut colors through chroma reduction and SDR lightness clipping. Leveraged CSS, algorithm design, and color theory to align rendering behavior with specifications, ensuring more reliable and consistent color output across browsers and platforms.
