Common pitfalls

• Duplicating fields instead of using extends.
• Implementing Panel UI logic in templates instead of blueprints or plugins.

Workflow

1. Clarify the content model, required fields, and Panel UX expectations.
2. Call kirby:kirby_init and read kirby://roots.
3. Inspect existing blueprints and patterns:
   • kirby:kirby_blueprints_index
   • kirby:kirby_blueprint_read
4. Use Panel reference resources for field/section choices:
   • kirby://fields
   • kirby://sections
5. Check plugin surface when custom Panel UI is needed:
   • kirby:kirby_plugins_index
   • kirby://extensions
6. Search the KB with kirby:kirby_search (examples: "blueprints reuse extends", "programmable blueprints", "custom panel field", "custom panel section", "panel branding").
7. Implement minimal, convention-aligned YAML/PHP; prefer extends and shared sections over duplication.
8. Validate by re-reading the blueprint (kirby:kirby_blueprint_read) and verifying frontend output with kirby:kirby_render_page when relevant.
