How people use it
A launch page, a cheap storefront, or a meeting point with a coordinate you can say out loud.
A product team claims a sector near the core, paints a world in their colour, and points the link at the launch.
A shop on the rim grabs an open planet for £5, writes one line, and sends people to checkout.
A community posts G04 · S10 in chat. New people open the map, find the glow, sign the book, and come back to the same address.
