Contrast Check
Calculates the WCAG 2.x contrast ratio between two colors, grades it against the AA and AAA thresholds for body text, large text and non-text UI parts, and finds the closest shade that passes. Use when someone asks to "check the contrast", "is this text readable on this background", "does our palette meet WCAG AA", "fix the low-contrast text", "audit the design tokens for accessibility", or brings a failed contrast finding from an audit. Handles hex and rgb() values, alpha, whole palettes, light and dark themes and a CI gate.
