	jobs:
	# GitHub Actions can have path filters (i.e., the use of a "paths:" keyword
	# on the trigger definitions in the "on:" block earlier in this file). Path
	# filters would be the natural way to make workflows trigger only when the
	# desired files are affected by a pull request – except that the way branch
	# protection rules work today is: "If a workflow is skipped due to path
	# filtering [...] then checks associated with that workflow will remain in a
	# Pending state. A pull request that requires those checks to be successful
	# will be blocked from merging." Surprisingly, GitHub doesn't provide
	# guidance on how to handle this. Discussions about solutions sometimes
	# suggest hacky solutions (c.f. https://stackoverflow.com/a/78003720/743730).
	# The approach taken here is to forgo the use of path filtering rules in the
	# trigger condition, and instead, do our own filtering using a combination
	# of testing specific file patterns (in the changes job below) and "if:"
	# conditions on individual jobs in the rest of this workflow.
