# Build the static web app and publish it to the `acp-ui/acp-ui.github.io`
# repository, which GitHub Pages serves at https://acp-ui.github.io/.
#
# Auth: fine-grained PAT (PAGES_PUSH_TOKEN). The PAT is scoped to a single
# repository (acp-ui/acp-ui.github.io) with `Contents: Read and write` and
# no other permissions. Pushes happen over HTTPS, which is simpler than
# SSH on the runner and avoids the silent SSH handshake hang we saw with
# deploy keys.
