+/**
+ * check-leaf-engine-per-provider — a leaf loads the engine its PROVIDER asks for, and no other.
+ *
+ * THE BUG (card BUG-LEAF-PAGES-PRELOAD-MAPBOX-EVEN-UNDER-MAPLIBRE; measured by exp-shepherd at
+ * 577149af). generate-tree chose a leaf's engine peer at BUILD time, from the instance config, and
+ * baked it into
as static tags: mapbox-gl.css, the geocoder css, mapbox-gl.js and the geocoder
+ * js, all from api.mapbox.com. The provider is chosen at RUNTIME (resolveMapProvider:
+ * profile-config.provider → ?provider= → window.MAP_PROVIDER → mapbox). So a partner that embeds a
+ * leaf with ?provider=maplibre still made its visitors' browsers fetch 4 files from Mapbox, sending
+ * every visitor's IP to a company the partner chose not to use. No project rule permits that.
+ *
+ * WHAT IS ASSERTED, on THIS checkout's served tree (every leaf in the manifest, instances included):
+ * MAPLIBRE every leaf at ?provider=maplibre makes ZERO requests to any *.mapbox.com host; a MAP
+ * leaf must also still draw (a canvas with a live GL context, window.maplibregl defined),
+ * so a fix cannot pass by breaking the map.
+ * DEFAULT every MAP leaf at its default still DRAWS, with the SAME engine it drew with before.
+ * The engine is read from the canvas that drew (mapboxgl-canvas / maplibregl-canvas), not
+ * from which globals exist: some leaves are MapLibre by design (prayer-walk-planner, the
+ * ".../maplibre" instances), and a peer that merely loaded Mapbox proves nothing.
+ * --baseline measures that tree too (e.g. main, with the static peer) and requires, per
+ * leaf: the default pass draws with the baseline's engine, and the maplibre pass draws with
+ * MapLibre wherever the baseline drew a map at all. Without it, a map leaf must simply draw.
+ * Paint here is a floor, not the verdict on looks: verify-map-paint and check:gospel-map-paints judge
+ * the map itself.
+ *
+ * USAGE node internal/check-leaf-engine-per-provider.mjs [--dir ] [--only a/b,c/d]
+ * Run through internal/browser-slot.sh.
+ * @browser-slot-max-hold 2700
+ * EXIT 0 pass · 1 a leaf calls Mapbox under maplibre, or a map stopped drawing · 75 not measured.
