Functions
bool	mm::core::isUrlSafeId (std::string_view s)
	Whether s is a valid URL-safe identifier usable as a path segment and pub/sub topic.
template<typename T >
std::optional< T >	mm::core::parseHexOrDec (std::string_view s)
	Parses an unsigned integer from a string in decimal or hexadecimal notation.
std::string	mm::core::toHex (std::span< const uint8_t > bytes, std::string_view separator={})
	Formats bytes as uppercase hexadecimal.
std::optional< std::vector< uint8_t > >	mm::core::fromHex (std::string_view hex)
	Decodes a continuous hexadecimal string into bytes — the inverse of toHex.
template<typename T >
std::array< uint8_t, sizeof(T)>	mm::core::toBytes (T value, std::endian order=std::endian::little)
	Encodes an integer into a fixed-width byte array in the given byte order.
template<typename T >
T	mm::core::fromBytes (std::span< const uint8_t > bytes, std::endian order=std::endian::little)
	Decodes an integer from a raw byte buffer interpreted in the given byte order.
