Free planner route

This route is where we can surface a lighter version of the planner for trial users: fewer steps, simpler focus controls and no advanced height shaping until they upgrade.

• Single shared planner engine underneath
• Future capability limits applied by route and tier, not by duplicating files
• Clean upgrade path into the full member planner

What unlocks later

The member planner path is ready for the full commercial feature set: height profiles, advanced focal logic, validation, Google Earth exports, planning objects and whatever we add next.
