Version 2.2.0-contrast-detection-fix (2025-12-09)

This release fixes three critical issues in the WCAG contrast checking functionality that were causing false positives and incorrect reporting.

Gradient Background Detection ✅
- Problem: Text on gradient backgrounds was incorrectly reported as white-on-white (1:1 ratio)
- Fix: Enhanced gradient detection to walk up the DOM tree and find gradients on parent elements
- Impact: Eliminates false positives for text on gradient backgrounds (e.g., hero sections with gradient overlays)
Solid Background Priority ✅
- Problem: Gradient backgrounds were incorrectly applied to elements with solid backgrounds
- Fix: Modified gradient detection to stop when encountering solid backgrounds - only applies gradients when no solid background exists between element and gradient
- Impact: Ensures accurate background color detection for elements with solid backgrounds
Child Element Text Color Detection ✅
- Problem: Tool used parent element's color (e.g., <a>) instead of child element's color (e.g., <span>)
- Fix: Added logic to check visible child elements and use their text color when present
- Impact: Accurate text color detection for complex DOM structures with styled child elements

Modified Files:

daemon/daemon.go - Lines 9152-9220: Enhanced analyzeGradientContrast() function
daemon/daemon.go - Lines 9305-9340: Updated background detection logic
daemon/daemon.go - Lines 9257-9322: Enhanced text color detection

Version Updates:

Test cases that now work correctly:

✅ White text on gradient backgrounds (e.g., linear-gradient(rgb(12, 90, 201) 0%, rgb(0, 0, 0) 100%))
✅ Text on solid backgrounds with gradient ancestors
✅ Links with styled child spans (<a><span style="color: ...">text</span></a>)
