# جسون — JSON serialization and deserialization
# =============================================================================
#
# What this teaches:
#   • JSON type conversions using `↦` — converting between `جسون`, `قيمة`, and concrete Faber types
#   • the `@جسون` annotation for custom field naming and genus-level JSON configuration
#   • roundtrip serialization with `json.stringify()` and deserialization with `json.parse()`
#
# Common mistakes:
#   • Applying @ جسون to a non-genus declaration — @ جسون is only supported on صنف declarations and their fields.
