Replace the full build+publish flow with a tiny inline shell step that
emits two static HTML pages (out/index.html and out/master/index.html).
Each one carries:
<meta http-equiv="refresh" content="0; url=https://loto.miti99.com/">
<script>location.replace("https://loto.miti99.com" + ...)</script>
The script preserves path / query / hash, so
/loto/ → loto.miti99.com/
/loto/master → loto.miti99.com/master
/loto/?x=1 → loto.miti99.com/?x=1
Cloudflare Pages stays canonical; this change just stops GH Pages from
serving a stale duplicate of the app and points old links at the live
domain instead.
The build:gh npm script is kept as a manual escape hatch for the rare
case where someone wants to deploy a real GH Pages copy by hand.
.github/workflows/deploy-github-pages.yml runs `npm run build:gh` on push
to main and uploads build/ via actions/upload-pages-artifact@v3 +
actions/deploy-pages@v4.
The build:gh script sets BUILD_PROFILE=gh, which switches svelte.config.js
basePath to /loto so assets resolve under tiennm99.github.io/loto.
Cloudflare Pages keeps deploying in parallel via the CF dashboard
(npm run build, root basePath, loto.miti99.com). Two URLs, no conflict.
