WalkthroughThe logic for setting the map's zoom and center after fitting bounds has been reordered. Now, the map sets the zoom level first if provided, then pans to the center if specified. A new variable Changes

126-133: Add missing semicolon & verify Handlebars truthiness in zoom block.The default zoom fallback on line 131 is missing a terminating semicolon, which breaks consistency with the surrounding statements:
- map.setZoom(maxZoom, {animate: false}) + map.setZoom(maxZoom, {animate: false});Also, confirm that the Handlebars
#if zoomand#if geojsonchecks behave as expected for all numeric zoom levels (e.g.,0vs.undefined).
135-142: Parse center coordinates as numbers before panning.Currently the template passes raw substring values (strings) into
L.latLng, which may lead to unexpected type coercion. Consider converting to numbers (and trimming whitespace) for robustness:- map.panTo(L.latLng('{{ center }}'.split(',')[1], '{{ center }}'.split(',')[0]), {animate: false}); + // split "lng,lat" into numeric [lng, lat] + const [lng, lat] = '{{ center }}'.split(',').map(s => parseFloat(s.trim())); + map.panTo(L.latLng(lat, lng), {animate: false});

When using geojson, first the map is panned to the provided center, and then it's zoomed in to the desired level.
Because of rounding errors, the center will be off.
By changing the order of operations (first zoom, then pan), the issue is fixed.
