 4. **Embed everywhere.** Press the map's **Share button**: *Share Link* is the map's own page,
    *Add to Your Website* is the embed code — both carry the full URL of whatever host serves your
    maps (plus a `utm_source` tag on the generated pages, so every site's traffic is measurable).
-   Verified places a pasted embed works: team websites and WordPress (Custom HTML block),
-   Squarespace (Code block — iframes need a Business or Commerce plan), Wix (Add → Embed → HTML

 5. **Train the trainer.** Teach each team to use the Share button to embed the map — then teach
    them to train the *next* team the same way. The movement doesn't hang on one mobilization
    team: every team that carries the map can multiply it.
