//Runtime ABI interrogation
//
//  The constants above are compile-time: they bake into the consumer, so they
//  describe the headers the consumer was BUILT against and can never reveal a
//  mismatch with the library it is actually LINKED to. That made
//  `ARIA_ABI_VERSION` decorative — nothing in the project read it.
//
//  These two functions are compiled into the shared library, so comparing
//  them against the constants detects exactly that mismatch.
