// Keyless boot-chain smoke over the REAL carrier: startWebServer + entry
// graph (__DSH_BOOT__ web2 shape) injection + built shell dist in a real
// chromium. First describe: graph injection + the fail-loud half. Second
// describe: the settled success pass — all nine REAL tsdown bundles load
// through the module system + vendored Loader chain in ?fixture mode (the
// infrastructure four ride the immediately prefetch tier, the UI rows fetch
// on demand), the three-column frame appears in one flip, and the resident
// question completes through the real UI stack. The full model round lands
// in smoke-real under the W5 real-host standard.
