# Tina4 Python — ASGI production image. Generated by
# `tina4 deploy docker --runtime asgi`.
#
# WHEN TO PICK THIS. The default image runs `tina4 serve --production`, which is
# one event loop in one process. This one hands the application to a real ASGI
# server so you get ITS process model: uvicorn workers, hypercorn's HTTP/2 and
# HTTP/3, or granian's Rust loop. Reach for it when one loop is no longer
# enough, or when your platform already standardises on an ASGI server.
#
# Tina4 exposes a plain ASGI 3 callable, so any compliant server works. The
# three below are pre-installed; swap TINA4_ASGI_SERVER for whichever you run.
#
# THE BOOTSTRAP MATTERS. asgi.py calls tina4_python's asgi(), which discovers
# src/routes BEFORE handing the callable over. Pointing a server straight at
# `tina4_python.core.server:app` starts a working application with NO ROUTES IN
# IT - measured: /hello answers 404 through the bare app and 200 through
# asgi(). That failure is silent, so the entry point is generated rather than
# left for you to discover.
