Launch collection / 01

Three complete worlds.
Zero generic recolors.

Each theme has its own scene direction for discovery, deep work, and code review — plus the components that hold everything together.

Dark

Cinematic mythology

Monkey King

齐天大圣

Myth, forged into focus.

Dark

Orbital night

Aurora Terminal

星港夜航

A quieter station for ambitious work.

Light

Botanical daylight

Cloud Garden

云上花房

A bright place to think clearly.

Beyond wallpaper

One visual system.
Every working state.

A good theme disappears when you focus. It keeps native interaction intact, respects the meaning of a diff, and stays readable when the session gets long.

  • ✓ Semantic component roles instead of screenshot coordinates
  • ✓ Separate Home, Task, and Diff scene direction
  • ✓ Dark and light contrast quality gates
  • ✓ Tested across four viewport sizes and sidebar widths
01Home

One orbital panorama runs beneath the sidebar and workspace without a visible seam.

02Task

Low-detail observation lighting keeps code and long responses comfortable to read.

03Diff

Cool, restrained geometry frames review work without competing with changes.

Built to be reversible

Change the atmosphere,
not your workflow.

01

Choose a world

Start with a complete visual system, not a loose wallpaper or a one-screen mockup.

02

Apply locally

The macOS companion verifies the official app and applies a restricted, data-only theme runtime.

03

Restore anytime

Pause the theme or return to the official experience without changing your projects or conversations.

Our goal is not to blur your photo behind a window. Studio will turn a prompt or reference image into a coordinated theme across every Codex surface, then validate it before packaging.
