GratisGIS v0.9.113

Fixed

• Maps showed a basemap but no data. Since 0.9.110 every vector and
  GeoJSON layer in the portal rendered nothing: MapLibre 6 ships a
  worker that imports a second file, the build shipped the worker on
  its own, and the worker died on its missing import before it could
  parse a single tile. Nothing reported it, because raster tiles decode
  without the worker, so the map still panned and zoomed normally.
  Both files are now served together, the build fails if a future
  MapLibre release adds another one, and the app logs a named error if
  the worker is ever unreachable again.

• One broken layer no longer takes a whole map down with it. A saved
  tile layer missing its URL threw inside MapLibre's render loop on
  every frame, which stopped every other layer on that map from
  loading. Such a layer is now skipped, with a console warning naming
  the item, and the rest of the map draws.

• Viewer apps stopped covering a map's own layer with a recoloured
  copy of itself. A viewer target that the referenced map already
  draws now reuses that layer and keeps the author's styling, instead
  of stacking a purple duplicate on top. Editors are unchanged.

• pnpm dev works from a fresh clone again. The MCP server's absent
  token no longer aborts the whole dev run, and the workspace packages
  are built before the dev servers start. CI now runs pnpm dev from
  a clean checkout so this cannot regress unnoticed.
