"""Syntax-parse every first-party template so a broken tag fails the unit lane.

The app only renders a handful of templates in unit tests (e.g. the login page),
so a Jinja syntax error elsewhere would otherwise ship green. env.parse() checks
syntax without resolving extends/includes/imports — enough to catch an unbalanced
or mistyped tag across the whole template tree (e.g. the base.html layout).
