next.config.js sets output: 'standalone', but Next.js does not copy public/
or .next/static/ into .next/standalone — that is a documented manual step.
Skipping it shipped new server code referencing new chunk hashes while the
old chunks stayed in the standalone tree, so those requests 404'd, React
never hydrated, and pages hung on "Loading session..." while the API kept
returning 200.
