0002 # Fast pre-commit checks for swf-monitor — target: under ten seconds.
0003 #
0004 # Encodes the exact invocations (venv, env, manage.py) so no session has to
0005 # rediscover them. Checks only what changed: compiles modified .py files,
0006 # runs the Django system check once, and lints modified templates for the
0007 # two known silent page-breakers (unterminated one-line {# #} comments,
0008 # unbalanced double quotes on tag-bearing lines).
0009 #
0010 # Usage: bash scripts/pre-commit-checks.sh   (from anywhere in the repo)
