BuildZIM walks a cloned host directory, turns every file into a content entry with a MIME inferred from its extension, picks a main page, and adds the standard metadata plus a mainPage redirect. state.json is skipped. BuildBinary appends the archive to a copy of kage behind a KAGEPCK1 trailer, and Embedded detects that trailer at startup so the binary serves itself. Handler maps / to the main page and /path to a content entry, the same handler the embedded viewer uses.
