TYP207 — face is not dyn-safe

Subsystem	Type checking
Severity	error

dyn Face requires every method to take self, return something other than Self, and carry no method-level type parameters (Clone.clone -> Self precludes it). Use a generic bound <T: Face> instead, or pick a dyn-safe face. See spec/faces.md §“dyn-safety”.
