Deploy my-app to GitHub Pages at niteshacars.in

Adds a workflow that builds my-app and publishes it to GitHub Pages, plus
the CNAME for the custom domain.

The workflow installs with `npm ci`, lints, builds, and uploads my-app/dist
as the Pages artifact. It triggers on pushes to main that touch my-app/, and
on manual dispatch. Because it is scoped to main, merging is what deploys;
nothing publishes from a feature branch.

`public/CNAME` is copied verbatim into dist/ by Vite, landing at the site
root where Pages looks for it.

Vite's default base of '/' is correct here: a custom domain serves from the
root, and the built asset paths are root-relative to match.

Verified by running the workflow's exact steps locally -- npm ci, npm run
lint, npm run build -- and confirming dist/ contains CNAME, index.html with
root-relative asset URLs, and the hashed JS/CSS bundles.

Deploying still needs two manual steps that cannot be done from here:
enabling Pages with the GitHub Actions source, and pointing DNS at GitHub.

+## Deployment
+
+Deployed to GitHub Pages at <https://niteshacars.in> by
+`.github/workflows/deploy-my-app.yml`, which builds this directory and
+publishes `dist/`.
+
+It runs on pushes to `main` that touch `my-app/`, and can also be started
+by hand from the Actions tab (Run workflow).
+
+`public/CNAME` holds the custom domain. Vite copies `public/` into `dist/`
+verbatim, so the file lands at the site root where Pages expects it.
+Removing it reverts the site to the default `*.github.io` address.
