The repo mixed variants such as center/centre and color/colour, so a name could be spelled either way and searches missed half the hits. Standardize on the US spelling, matching .NET's own APIs (Color, Center). Wire values owned by other systems keep their spelling: the material ledger's "Cancelled" hold status and GitHub's "cancelled" job status. No behavior change beyond the spelling of a few status messages. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
