vtcode-ui

Root AGENTS.md | Unified UI: design system, theme registry, TUI framework. Consolidated from vtcode-design and vtcode-theme.

Modules

Area	Path
Design system	design/ — color conversion, style bridging, layout, diff, panel primitives
Theme registry	theme/ — ThemeStyles, runtime state, syntax theme resolution
TUI framework	tui/ — session, widgets, runner, markdown rendering, config

Rules

• design and theme are re-exported at crate root (pub use design::*; pub use theme::*) for backward compatibility with the old standalone crates.
• publish = false — internal crate, not published to crates.io.
• tui/core_tui/ owns the full terminal session lifecycle; tui/ui/ has reusable widgets (markdown, interactive list).
• tui/config/constants/ holds TUI-specific defaults — keep them here, not in vtcode-config.
• Snapshot tests live in tui/core_tui/widgets/snapshots/.

Gotchas

• vtcode-commons provides anstyle_utils gated behind a tui feature — the style bridging in design/ depends on it.
• The crossterm dependency enables event-stream and osc52 features; do not duplicate these in downstream crates.
