/// The two are different questions, and mixing them up is what made the old rules delegate between
/// vendors until they called each other in circles. A provider is where a request goes; a vendor is
/// whose model answers it. Llama comes from Meta whether it arrives through Groq, Fireworks, or a
/// local Ollama.
///
/// A rule may bind itself to a vendor, which matters where the same name means two different models
/// depending on who made it. It is also what a gateway declares when it unwraps a name such as
/// "anthropic/claude-sonnet-4-0".
///
/// This list grows with the families being ported. Only vendors whose models the app already has
/// rules for are named here; adding a member is part of adding the family, not a step of its own.
