| # Builds the Astro site and publishes it to GitHub Pages. | |

| # Why an Actions workflow instead of plain "deploy from a branch": | |
| # the cohort directory is fetched from the Google Sheet at BUILD time, | |
| # so the host has to actually run `npm run build` with the SHEET_CSV_URL | |
| # secret available. This workflow does exactly that, then hands the | |
| # finished `dist/` folder to GitHub Pages. | |

| push: | |
| branches: [main] | |
| # Lets you trigger a rebuild by hand from the Actions tab — | |
| # useful when you want a Sheet edit live immediately. | |
| workflow_dispatch: | |
| # Rebuild once a day so edits to the Google Sheet go live without | |
| # anyone pushing code or clicking a button. 09:00 UTC ≈ 5am US Eastern, | |
| # so changes are live by the start of the day. Cron is always in UTC. | |
| # Note: GitHub may delay scheduled runs under load, and pauses the | |
| # schedule after 60 days with no repo activity (a push re-arms it). | |
