docs: Serializes a SafeStyle into its opaque protocol message representation.
  
  <p>Protocol message forms of this type are intended to be opaque. The fields of the returned
  protocol message should be considered encapsulated and are not intended for direct inspection
  or manipulation. Protocol messages can be converted back into a SafeStyle using
  {@link #fromProto(SafeStyleProto)}.
