`kcode-kmap-size` reports an intentionally approximate token footprint for the
current text fields in a Kweb Kmap.
It counts the short name, short description, and long description of every
current node, and reports long descriptions separately. It excludes history,
provenance, connections, objects, and all other storage. The estimate uses one
token per four Unicode characters; it is not a model tokenizer.
See `Documentation.md` for the complete API.
