frontend-production-quality

Use before implementing UI changes or frontend PRs. Enforces TodoWrite with 18+ items. Triggers: "accessibility audit", "WCAG", "Lighthouse", "screen reader", "a11y", "NVDA", "VoiceOver", "keyboard navigation", "focus indicator". For "Core Web Vitals" in frontend/UI context, use this skill. For pure backend/API performance optimization, use performance-optimization instead. If thinking "WIP doesn't need this" - use it anyway.
