Docker: moved all docker files to docker/ tree (was conflated with upstream Dockerfile at root + server/Dockerfile). Single container now: caddy (front, serves static + proxies /api /ws) + node backend (internal :4001). Node never exposed. entrypoint.sh runs both. Compose: one service. Blank page root cause: storage adapters had inconsistent module systems. firebase.js = ESM (export). ws.js + memory.js = CJS (module.exports). CRA prod build = ESM strict -> CJS runtime crash, blank root. Dev mode lenient, masked bug. First ws prod build (docker) = first exposure. Never dev/prod split intended; just inconsistency from M2 era. Fix: all adapters ESM. ws.js lazy-loads 'ws' pkg via dynamic import() (Node/jest only; browser uses global WebSocket). index.js static imports. server jest: added babel.config.js (preset-env, node target) to transform ESM for jest. Test: src/tests/StorageEsm.test.js — 4 tests grep all adapters for module.exports / require(). Regression guard catches CJS leak. Verified: docker page renders (root 4534 chars, UI visible). server 24 green, shared 90 green, FE ESM 4 green.
