name: playground

# updates the playground (imagescript/playground, try.imagescript.dev) to a version of imagescript: its dependency,
# built to check it, committed and pushed to its main branch, which deploys it. release.yml runs it for regular
# releases; can also be run by hand from the Actions tab (empty version: the latest on npm). Needs the
# PLAYGROUND_DEPLOY_KEY secret: the private half of a deploy key with write access to the playground's repository
# (without it nothing is updated)
