# The web app (apps/fieldcraft-web, docs/web.md) on GitHub Pages: https://jyviko.github.io/fieldcraft/
# After SolidCraft's pages.yml (MIT OR Apache-2.0; see ATTRIBUTION.md).
#
# A push to `main` (a release; main holds released code only) builds the app with Trunk (release,
# wasm-opt) and deploys it. A merge to `develop` that touches code builds it without deploying, so a
# broken web build shows up before the release. A manual run builds the branch it runs on and
# deploys only from `main`. Needs Settings › Pages › Source = GitHub Actions, and `main` allowed
# by the github-pages environment's deployment branches.
