Contract
- contentDisposition() generates attachment disposition without parameters when called with no arguments
- contentDisposition(filename) formats attachment disposition header with quoted basename
- contentDisposition(filename, { type }) supports custom disposition types including inline
- contentDisposition(filename) generates ISO-8859-1 fallback filename and RFC 5987 UTF-8 encoded filename* parameter for Unicode filenames
- contentDisposition(filename, { fallback }) supports custom fallback filename string and boolean false to omit fallback
- contentDisposition.parse(header) parses disposition header string into type and parameters map
- contentDisposition.parse(header) decodes RFC 5987 extended UTF-8 parameters into standard parameter keys
- contentDisposition.parse(header) throws TypeError on invalid arguments or malformed header syntax
