RGB channel validation & HEX packing

RGB → HEX starts with numeric channel validation. Detect clamping, quantize alpha to a byte, and show both six-digit and eight-digit packed forms.

The alpha channel is quantized from 0–1 to 0–255 for eight-digit HEX. Strict validation avoids silently changing invalid input.

Color and accessibility boundaries

HEX/RGB/HSL/HSV/OKLCH conversions are numerical color-model operations. CMYK output is an RGB-derived approximation rather than ICC-profiled print proofing. WCAG contrast ratios measure luminance contrast only and do not certify a full interface. Color-blindness previews are design simulations, not medical tests.
