what is codex-dream-skin fr?

Codex Dream Skin is an unofficial tool that lets someone change how the Codex desktop app looks, without touching the official application files or code signing. It restyles the home screen, sidebar, suggestion cards, and input area with a chosen theme, while every button and text field keeps working exactly as before. Users can pick from five built in themes or generate a new one from their own image, and can switch back to the official look at any time. The main supported platform is macOS, on both Apple silicon and Intel machines, and it is aimed at people with no coding background. After opening the official Codex app at least once, a person just double clicks a command file in the macos folder, picks an image in the window that appears, types a theme name, and waits for Codex to relaunch with the new look applied. The install process also drops several ready made shortcuts on the desktop for everyday launching, generating a new theme from a new image, tweaking the current theme, verifying the install, and restoring the original appearance. A menu bar switcher, built on the SwiftBar project, is also available so someone can flip between the five built in themes or turn on automatic theme rotation every 30 minutes. Windows support exists but is described as experimental, since the author has no Windows machine to test it against, and it currently cannot generate a theme from a custom image. It needs Node.js installed and uses PowerShell scripts to install, start, and restore the app. Under the hood, the theme is applied by connecting to the official Codex app through the Chromium DevTools Protocol, listening only on the local loopback address. The README states it does not modify the official app package, does not touch API keys or model provider settings, and only adjusts appearance related configuration that can be fully restored.
