# Rebuilds src/modules/loldle/champions.json every Monday 06:00 UTC by
# scraping loldle.net's JS bundle (sole source of truth for classic-mode
# fields). Opens a PR if the output changed. Manually triggerable from the
# Actions tab.
#
# Note: the bundled data ships with the Worker — the change only takes effect
# after `npm run deploy` is run on the updated main branch.
