Accessibility and Usability Fitness Review

Analyze frontend code (HTML, CSS, JavaScript, templates, components) for accessibility and usability fitness against WCAG 2.1 AA baseline and usability best practices.

Domain Knowledge

• references/rubric.md is the scoring source: severity levels, 1-10 anchors per dimension, N/A rules, and the Overall formula. Read it first; it is short. Scores taken from it are repeatable; improvised ones are not.
• references/checklist.md is what to check, file by file, with the WCAG thresholds.
• scripts/contrast.py computes contrast ratios. Every ratio in a report comes from it, because guessed ratios are the most common wrong number in accessibility reviews.
• references/wisdom.md is optional background, auto-generated from the three articles above (about 2,500 lines). Grep it by heading for a specific question (grep -n "^#" references/wisdom.md); never read it whole.

Configuration

Invoke the resolver CLI to obtain effective weights and thresholds for the review target. Never load fitness-config.json directly.
