nightly.yml

name: Nightly Build

# Daily / on-demand builds, published as a rolling pre-release on GitHub.
#
# Difference vs release.yml:
#   - release.yml  → triggered by `v*` semver tags, becomes the "Latest" stable release
#   - nightly.yml  → continuous interim builds, marked prerelease, single rolling tag
#
# Trigger options:
#   - Manual: Actions tab → "Nightly Build" → Run workflow
#   - Push to main: every commit (disabled by default; uncomment the push block)
#   - Daily cron at 04:00 UTC

on:
  workflow_dispatch:
  schedule:
    - cron: '0 4 * * *'
  # Uncomment to also build on every push to main:
  # push:
  #   branches: [main]
