From 4fd60293fa3998e0facef130be7618ea8e7b0fce Mon Sep 17 00:00:00 2001 From: Bendik Aagaard Lynghaug Date: Thu, 24 Sep 2026 21:17:28 +0200 Subject: [PATCH] A field can be a place, and a question can be about one `type: location` puts a pin on a map and stores {lat, lon, zoom}; a record that holds one renders as a still, on a desk and in any resource card. `place:` on a question is the counterpart to `event:`: event makes a page an occasion with a time, place makes it somewhere, shows the map under the question, and opens any location field on the page there instead of on the globe. Every tile and every still is fetched by portal and served from this origin (src/maps.rs, MapLibre vendored in public/), so a page with a map on it still talks to nobody but us: no third-party request, no consent banner, and the token never leaves the server. MAPBOX_TOKEN unset turns the whole thing off, the way GARAGE_* does for uploads.
