Velvet Observatory
Codex theme.

A burgundy observatory with antique brass instruments, celestial depth, and a calm left-side reading field.

Layout previews

Home and active task.

Home and task states use one consistent coded Codex-like shell over the theme artwork. They are illustrative previews—not live Codex captures.

Designed for real work

Quiet luxury for long-range thinking.

Velvet Observatory pairs a dark canvas with a visual direction built around burgundy, brass, celestial 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.
