Since 2026-09-28 resolveMapProvider returns MapLibre for 'auto' whether or not a token is present;
only an explicit provider selects Mapbox. Four comments still said "Mapbox when a token is
available": useMapProvider.js's own header (and its note on the `token` argument),
useMapInstance.js at the provider option, check-provider-switch.mjs's contract note, and the
PROVIDER note that generate-tree writes into every leaf page.
The leaf page's note now says what the page does: it finds a token first only when one is on offer,
because place search uses one on either engine, and the element decides the engine. The 64 leaf
pages are regenerated and differ only in that note. The three JS files change in comments only
(compared minified, without renaming).
