<!-- ============================================
  ACES ARCADE — the engine, in a browser.

  There is NO build step and NO bundle. This
  page fetches the very same CommonJS modules
  that `node test.js` runs (core.js,
  calculator.js, store.js, nav.js, ledger.js,
  platform.js, parse.js, version.js ...) and
  wires them with a tiny require() shim below.
  The site serves its own source: view-source
  is the real program.

  Isomorphism, demonstrated:
  - same decide/evolve/react as the CLI
  - the 'speak' EFFECT runs on the browser's
    TTS (Text To Speech) processor here — and
    is GATED by the nav archetype's folded
    sound setting.
  - NAVIGATION IS STATE: the tab strip is the
    nav archetype; the route table is a
    parser-printer (parse.js). decide()
    validates a destination by PARSING it;
    react() PRINTS state into location.hash.
    Deep links replay the same road inward.
  - REPLAY drops state and refolds the log,
    live, because state is only a cache.
