// client files then 403 and hydration never runs (so e.g. the Turnstile widget
// on /admin/login never renders). Allowing the RESOLVED node_modules keeps
// worktree dev/e2e working; in a normal checkout the realpath is
// ./node_modules, already allowed. realpathSync throws before `npm install`,
// where the literal path is the right (and only possible) answer.

// Actions (deploy.yml), where these vars are always set — so every fork gets
// its OWN repo URL, never a hardcoded upstream link that would 404 on commits
// that only exist in the fork. Local/dev builds have neither var and the
// footer omits the line. The composition lives in build-info so it can be
// unit-tested; this file is only reachable through a real build.
