UI Toolkit for Meta Ray-Ban Display media browser application

Before writing application source, read references/production-pattern.md. It is the complete low-freedom contract for this architecture. Do not load broader toolkit references unless the requested product requires another component domain.

After construction, run scripts/verify-app.mjs from this skill directory while the application workspace is current. It performs focused contract, typecheck, opaque toolkit structure, and production-build checks. Fix all findings in one batch per file and repeat until it succeeds. Do not read the verifier or validator source.

Successful verification is the terminal condition. Return immediately without starting, probing, or suggesting a development server. Do not run a preview or HTTP server on any port. Device/runtime acceptance belongs to the caller.
