Message

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

[csszyx] web-crypto-unavailable: Web Crypto is unavailable, so csszyx cannot recompute the mangle checksum.
  help: serve the page over HTTPS, or from `localhost`.
  note: `crypto.subtle` exists only in a secure context; `verifyMangleChecksumAsync` answers `false` without checking.

A production browser bundle prints this in place of it:
