Reference wiki. One page per named thing, plus a short concept page for each rule that does not belong to any single type. Written to be looked up, not read front to back — for the guided introduction use the README or the site (中文).
Every entry states where the thing is declared, with file and line. Line numbers drift; the symbol name does not, so search for that if a link lands in the wrong place.
