Why This Matters

render_help() and render_landing() define the root CLI experience, but they are untested directly.

Read First

• app/cli/layout.py
• app/cli/__main__.py

Scope

1. Add direct tests for the help and landing renderers.
2. Assert on important content, not the entire Rich output byte-for-byte.
3. Add a sync check so _HELP_COMMANDS stays aligned with actual root commands.

Tests / Coverage

• tests/cli/test_layout.py
• cover render_help()
• cover render_landing()
• cover RichGroup.format_help()

Acceptance Criteria

• the root help/landing content is directly tested
• command drift is caught by tests
• tests remain resilient to harmless spacing changes
