[RealTask]

Summary

• Add 30 original, searchable records for advanced product workflows, AI streaming, command palettes, filter persistence, account and billing, privacy and permissions, network failure recovery, accessible dialogs and comboboxes, data integrity, motion, and performance evidence.
• Merge the supplementary catalog with the existing 12-domain catalog in the offline search loader.
• Expand search synonyms and add validator smoke checks for the new coverage.
• Document research provenance, authoritative references, and evidence limits.
• Update README and root skill instructions to explain the expanded dataset.

Research basis

The guidance is original to MAX-DESIGN and references primary sources where relevant: WCAG 2.2, WAI-ARIA Authoring Practices, MDN accessibility guidance, web.dev Core Web Vitals, and Apple Human Interface Guidelines. The UI/UX Pro Max repository informed taxonomy comparison only; its data tables and scripts are not copied.

Verification

• Parsed both JSON catalogs and checked 119 combined records.
• Confirmed 30 supplementary records, unique IDs across the combined catalog, and required record metadata.
• Checked the edited JavaScript modules for syntax and simulated representative searches across new domains.
• Automated npm test has not been executed in a repository runtime in this session; please run it before merging.
