Is this an official DexThemes product?

DexThemes is free, open source, and community-built. It is not affiliated with OpenAI. This is a curated DexThemes palette, not a built-in Codex theme.

Does DexThemes modify Codex files?

No. DexThemes prepares an import string. Codex owns the final Appearance import and asks you to approve the change.
