# Codex Theme Studio

Turn a visual direction, brand system, or supplied image into a reversible Codex Desktop theme through loopback-only Chrome DevTools injection.

## Modes

- **Design**: prepare a portable theme directory and validate it without installing or restarting Codex.
- **Apply**: run the safety preflight, install the runtime, and import or create a theme. Obtain explicit authorization before restarting a running Codex app.
- **Verify or repair**: reproduce the affected route, run deterministic tests, Doctor, and live Verify, then repair only selector or layout failures supported by evidence.
- **Pause or restore**: Pause removes the active styling. Restore also stops the managed CDP session and returns Codex to the official appearance.

## Workflow

1. Read [capability-boundary.md](references/capability-boundary.md). Confirm the official macOS host, authorization boundary, and excluded targets.
