Licence

Use in unlimited end products incl. client/commercial; no resale/redistribution as a template, kit or dataset; no ML training. Survives cancellation for delivered versions.

Full terms: Motif template licence. Open-source parts keep their own licences (licenses.json, id lic-premium-field-checklist-1-0-2).

Ask your agent

Use Motif to activate the premium-field-checklist template and download it. Then adapt it for a climbing gym's route log: replace the content and imagery, keep the design tokens and every state in docs/STATE-MATRIX.md, and run check_design_contract before you finish.
