UI Toolkit for Meta Ray-Ban Display timed session 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 user explicitly requests an unsupported capability.

After construction, keep the application workspace as the current directory and run this skill's scripts/verify-app.mjs. Fix all reported issues in one batch per file and rerun until it succeeds. Do not read the verification script.

Successful verification is the terminal condition. Do not discover browser runners, start servers, repeat individual gates, or author substitute checks. Device/runtime acceptance is a separate caller-owned stage.
