Standalone performance guide for the Nitro V3 client, covering both
sides of the cold-load story so a deployer doesn't have to cross-
reference two repos to get from 60-90 s down to 4 s.
Sections:
1. Three Nitro-side changes that matter (code split, LoadingView with
real progress, remember-token URL capture)
2. Vite manualChunks — why vendor-first ordering matters, why pixi
stays inlined, expected chunk sizes after yarn build
3. LoadingView state model + the 12-stage progress table + the
pre-React shell template in scripts/write-asset-loader.mjs
4. Remember-token capture from URL → SetRememberLogin, with DevTools
verification of nitro.auth.remember localStorage entry
5. nginx gzip (the single biggest win at ~17x for JSON5) + 30-day
cache headers on gamedata + try_files manifest fallback
6. Windows + IIS equivalent — URL Rewrite + ARR reverse proxy to
Node, Dynamic Compression toggle, web.config snippets,
trade-offs (CPU cost, JDBC quirks, shared hosting caveat)
7. End-to-end verification probes — chunks present, gzip on, dir
fallback works, progress bar renders, remember-token persisted
