[kimteayon]

Summary

• add a production-oriented headless Surface Runtime with strict catalogs, atomic transactions, immutable snapshots, rollback, limits, and A2UI v0.8/v0.9 adapters
• add production Control Room demos for both protocol versions, including streaming updates, unsafe-component rejection, rollback, reset, and responsive layouts
• fix narrow-container overflow across the existing A2UI v0.9 demo suite
• add bilingual Runtime API, security, error, and migration documentation; replace the stale x-card README and package metadata

Verification

• TypeScript checks passed for packages/x and packages/x-card
• Biome and Remark checks passed
• browser QA passed for v0.8 stream, guard rejection, rollback, reset, documentation routing, and 390px layout with zero overflow
