What makes a good Codex theme?

Readable before decorative

A strong Codex custom theme keeps prompts, diffs, tasks, and navigation readable before it asks the background image to make an impression.

Quiet where text lives

Position the most detailed part of a Codex background away from the conversation and code columns. Use panel opacity and dimming to restore hierarchy.

Easy to review and restore

Prefer data-only theme recipes, transparent source code, a local-only workflow, and an explicit restore path.
