Claude's fullscreen diff panel takes the theme palette
A change merged into quattro renders the Claude Code fullscreen diff panel's background from the theme palette. Claude Code drops override keys it does not recognize, so an older Claude Code is unaffected.
Claude Code opens a diff panel beside the conversation in fullscreen mode. Its background comes from a theme key the Omarchy template does not set, so the panel renders in Claude's built-in gray next to a themed session.
The mix is a 5% background-to-foreground mix, just under the 6% used for user-message bubbles, so the sidebar sits darker than the message backgrounds.
