// RegisterBuiltins registers all normalizers shipped with this binary.

// This mirrors internal/sources.RegisterBuiltins, but note the selection model:
//
//   - sources are built by name (cfg.Driver -> factory)
//   - normalizers are selected by Match() (event.Schema -> first match wins)
//
// Registration order matters because feedkit normalize.Registry is “first match wins”.
// In weatherfeeder we avoid ambiguity by matching strictly on schema constants, but
// we still keep ordering stable as a best practice.

// If reg is nil, this function is a no-op.

	// Order here should be stable across releases to reduce surprises when adding
