+/// calling. None of it is true, and the app already knows better -- it asks every provider for its
+/// embedding models through a method of its own.
+///
+/// The Gemini one needs a rule of its own for another reason: its name begins with "gemini", so
+/// without one it would be read as a chat model of the family.
