/* TUI control: lights-out design system.
   Identity carried over from the original TUI dashboard: a pure black canvas,
   the terminal face (Source Code Pro), hairline rules and the Claude Code CLI
   glyphs (❯ prompt, ● turn and tool bullets, ✻ activity). Depth comes from
   neutral surface steps, never tinted greys. Orange marks the agent and live
   activity; white is the primary action; status colours carry meaning only.
   Order: fonts, tokens, base, controls, shell, home, conversation, dock,
   overlays, responsive. */
