Summary

Add an embeddable version of the events map so organizations can publish a filtered map/list view on their own sites.

Scope

• Add embed mode (for example via query param) that minimizes site chrome.
• Preserve map/list behavior and filter state in the embed.
• Ensure permalinked filters can be preconfigured by host pages.
• Ensure embed mode is responsive and works in constrained iframe heights.

Technical constraints

• Keep filter contract aligned with /events/map (from, to, tag, org, loc).
• Reuse existing map data/filter pipeline; avoid forked logic.
• Avoid requiring privileged/admin endpoints for public embedding.
• Keep attribution requirements visible for map tiles (OpenStreetMap/CARTO).
