is extracted from the `body-muscles` npm package:

Only the `id` and `path` (SVG `d` attribute) fields were extracted —
the `name` and `view` fields from the original source were dropped
during parsing and are not present in the vendored JSON here. If the
`name` field is wanted later (nicer display labels than the kebab-case
`id`), it's still in the original source files above.
