This page is the demonstration
Everything above is rendered from a plain text file the server owner edits themselves. Adding a rule means adding four lines and saving. No developer, no ticket, no waiting, and nothing else on the site can break while doing it. The changelog page works the same way.
{ title:"Value your life",
body:"Your character is afraid of dying,
because a person would be..." },
That is the whole format. On a live build the same idea extends to the store, except that half is read straight from the owner's real store, so it updates itself with no editing at all.
