The API moved to mathapi.tadrisino2.ir on 2026-09-26; api.math.tadrisino2.ir
no longer resolves. .env.production is the only place that names it.
deploy.sh fetches, runs npm ci and the type-check, builds into dist.next and
swaps it in only when everything succeeded, so the site is never served half
a build. The previous build stays in dist.prev for rollback, and a
hand-edited dist/config.js on the server survives the release.
