Core Philosophy

Accessibility (a11y) is not an afterthought compliance checklist to run the week before product launch. Accessibility is core design and software architecture. Designing for accessibility ensures that digital products are usable by people with visual, auditory, motor, and cognitive disabilities. Compliance with WCAG 2.2 (Level AA and AAA) is legally mandated under the Americans with Disabilities Act (ADA Title III) and European Accessibility Act (EAA).

4-Step Systematic Accessibility Review Protocol

Step 1: Color Contrast & Visual Perception (WCAG 2.2 SC 1.4.3 / 1.4.11)

1. Mathematical Contrast Ratios:
   • Body Text (< 18pt or < 14pt bold): Minimum 4.5:1 contrast ratio against background.
   • Large Text (>= 18pt or >= 14pt bold): Minimum 3.0:1 contrast ratio.
   • UI Components & Graphical Objects: Active borders, form input outlines, and icons must meet 3.0:1 against adjacent background.
2. Never Rely on Color Alone (SC 1.4.1):
   • Error states, status indicators, and chart lines must include text labels, icons, or distinct dash patterns in addition to color hues.
