+"""Regression test for Starlette 1.1.0+ TemplateResponse keyword-argument style.
+
+Prior to this fix, the three HTML routes called:
+    templates.TemplateResponse("name.html", {"request": request, ...})
+which passes the context dict as the second positional argument.  With the
+updated Starlette/FastAPI versions shipped in NixOS unstable (Starlette 1.1.0,
+FastAPI 0.136.3) that positional argument is the template name, causing Jinja2
+to receive a dict as a cache key and raise:
