Inject COLORFGBG (derived from the active xterm.js theme background via Rec. 601 luma) into the env of every PTY the server spawns. This gives Claude Code, Codex, and other TUIs a reliable light/dark signal so they can match the page theme. Windows ConPTY intercepts OSC 11 background-color queries and never forwards xterm.js's response back to the child, leaving TUIs stuck on their dark default. On a light coder-studio theme this surfaces as a stark black bar behind user messages. COLORFGBG is the only signal that survives the ConPTY layer. - TerminalSpec gains an optional themeBackground hex string forwarded through session.create / terminal.create command schemas - TerminalManager derives COLORFGBG once at spawn time and lets spec.env override when callers need to pin a specific value - useTerminalThemeBackground hook reads the active theme atom and is threaded through every session/terminal create call site
