Async fs.read_file_async<T> uses the same fs:lege route as sync fs.read_file<T>.

# =============================================================================
# async 仅 leget — async solum.read_file_async<T> uses the same solum:lege route as
# sync solum.read_file<T>.
# =============================================================================
#
# What this teaches:
#   • Async/sync proof pair — `solum.read_file_async<T>` and `solum.read_file<T>` share the
#     same host route; the async callable posture selects the async receive path
#   • Import syntax — `导入 取自 "norma:fs"` brings in standard library
#     modules
#
# Common mistakes:
#   • using an 调用 expression outside the AIR 车道 or confusing the async route syntax — `solum.read_file_async<T>` must be awaited from `异步入口`
#
# See also: 调用, 仅, 未来, 通道
# =============================================================================

# Async `调用` materialization through a standard-library proof pair.
#
# `solum.read_file_async<T>` is the async-posture twin of `solum.read_file<T>`. Norma currently
# declares the wrapper with compatibility `@ 未来`; callers consume it through
# the explicit morphology forms such as `等定`.
