removed-option

A plugin option that was removed and is no longer read.

• It is printed to the console. A production browser bundle leaves it out.

Message

A name in angle brackets is a value the message fills in.

inject-checksum

[csszyx] removed-option: `production.injectChecksum` was removed and was never read: every production build carries the hydration checksum and the census, whatever it is set to.
  help: delete the option.
  note: the census lists no classes when `production.mangle` is off, and the browser runs neither the checksum nor the census as script; see https://csszyx.com/docs/security/.

mangle-map-delivery

[csszyx] removed-option: `production.mangleMapDelivery` was removed and is ignored: the runtime mangle map is always registered from inside the JS bundle, and the built HTML carries no inline `<script>`.
  help: delete the option.
  note: a strict `script-src 'self'` policy needs no exception; `window.__csszyx` is opt-in through `production.mangleDebugGlobal`.
