A safer way to design an image background for Codex on Mac

Prepare artwork for a working interface

A beautiful wallpaper can become unreadable when panels, code blocks and status labels sit above it. Use a restrained focal point and preserve quiet regions for text.

• Use PNG, JPEG or WebP under the editor's stated limit
• Test both dense and empty screens
• Avoid placing high-contrast detail behind the composer and code output

Keep media local and inspectable

Local processing reduces unnecessary exposure of private or licensed artwork. A safe package should contain declared files with integrity hashes, not remote URLs or executable scripts.

Treat performance and contrast as release checks

Blur, transparency and video can increase power use and reduce text contrast. Offer a static or reduced-effects fallback and verify ordinary text at 4.5:1 contrast where practical.
