Top type. Everything is assignable to `Any`, nothing is assignable
out without a downcast.

Used as an escape hatch when interfacing with stdlib facilities
that haven't been ported to richer types yet (e.g., generic shape
data crossing a `tool` boundary). Treat as a refactoring target —
prefer concrete types in production flows.
