"""
transport_errors -- shared wrapper for provider network calls.

Wraps *unexpected* failures (network, bad JSON, malformed payloads) in
ServerError and lets typed provider errors (AuthError, RateLimitError,
GeoBlockError, ...) through untouched: callers rely on those to refresh
tokens or back off, so they must never be flattened into a generic error.

simpli keeps its own identical copy in providers/simpli/helpers.py until it
is switched over to this one.
