about

nx_maps_render.nx -- GEO-024 NISHI MAPS test output (v: render+interactive+basemap+search+route+polish): a sovereign, Google-Maps-like map VIEW rendered entirely by Nishi's own geo organs. It projects seeded geographic features (land, roads/route, geofence, place markers) through the sovereign WEB-MERCATOR projection (GEO-019b math: fx.nx CORDIC + log2, Q16.16) onto a pixel viewport, and EMITS a self-contained HTML+SVG document. The browser is only the sink -- NO Google, Mapbox, Leaflet, or proj4 in the path (ecosystem-only; HTML/SVG = last mile). Output -> web_assets/_maps_build/maps.html (serve at nishifamily.com/maps). Self-gating: the viewport CENTER must project to the pixel centre (W/2,H/2); verdict -> geo_map.log. license_tier: ORIGINAL
