  steps:
    # The key carries the workflow name: cache keys are write-once, so with one
    # key per commit the quickest workflow (lint) saved its near-empty cache and
    # the build never got to store its outputs.
    #
    # A push starts from an empty cache and saves only what this build produced,
    # which keeps the entry at the size of one build. Pull requests restore the
    # latest entry of the base branch and save nothing.
