Layout previews

Home, task, and narrow.

Home, task, and narrow states are rendered from a deterministic HTML/CSS Codex-like shell using fixed demo content. The renderer does not open Codex or read user data.

Designed for real work

Build in black. Ship in orange.

Codex Hub pairs a dark canvas with a visual direction built around black, orange, developer, brand cues. Its focal point sits away from the main reading field, while the coordinated surface and foreground colors keep tasks and code legible.

This first-party pack is local-first and reversible. It does not replace the signed Codex application or take ownership of system application directories. Advanced image backgrounds use the open-source compatibility layer only when the current Codex version supports it.

Included

Theme manifest and complete visual tokens
Landscape background with gradient fallback
Three responsive background layouts
Checksums and CLI installation guidance
Asset license and compatibility notes

Compatibility

Native color themes and advanced visual themes are separate compatibility paths. Image backgrounds are not represented as an official Codex feature unless the current app explicitly exposes them.
