This app needs WebGL2 to draw the map, and this browser has it disabled or unsupported — so the canvas stays black. Turning it on fixes it.
Brave: open brave://settings/system, switch Hardware acceleration ON, then Relaunch. Confirm at brave://gpu that WebGL2 reads “Hardware accelerated”.
Otherwise open golf.kampen.cc in Firefox or Chrome, where it already works.
