A custom theme family (Agent Zed Dark/Light) derived from One with the
accent surface — cursor, text selection, links, focus rings, icons, and
selected-item wash — recolored emerald, plus a subtle green tint on the
structural surfaces, matching the energy/eco-AI ethos. Set as the
system-aware default so it follows the OS light/dark preference.
