deploy-github-pages.yml

# Build static assets and publish to GitHub Pages (Settings → Pages → Source: GitHub Actions).
#
# If the live site shows a blank page, check View Source: if you see src="/src/main.tsx", GitHub Pages
# is still publishing the repo root (branch deploy) instead of this workflow's dist/ — switch Source
# to "GitHub Actions" below and redeploy.
#
# Required repository configuration:
# 1) Settings → Pages → Build and deployment: Source = "GitHub Actions"
# 2) Settings → Secrets and variables → Actions → add secret:
#    VITE_TRANSCRIBE_URL = https://<your-api-host>/api/transcribe
#    (Your FastAPI server must allow this site's origin; set CORS_EXTRA_ORIGINS on the server,
#     e.g. https://<github-username>.github.io )
#
# The workflow sets VITE_BASE_PATH to /${{ github.event.repository.name }}/ so asset URLs match
# https://<user>.github.io/<repo>/.
