Rerouted (retagged, verified). The tag now points at a different commit than when this version was published. The Lamdera package server serves a copy recovered from https://github.com/newmana/chroma-elm.
What we checked: Tag 10.1.1 now points at c09d06b75e39, not the published commit. Rebuilt with git archive from commit 51684c31ed38 of https://github.com/newmana/chroma-elm (zip prefix newmana-chroma-elm-51684c3/, America/Los_Angeles times): the zip is byte-identical to the one package.elm-lang.org recorded, SHA-1 c7cb31d365d767882e728ab60ac1a1d66f0fd85f.
The Lamdera compiler uses this copy and prints a one-line notice saying so. elm itself fails to download this version.
