/*
 * voice-assistant.css — JARVIS-style full-screen overlay for Lexxie voice mode.
 * Three layers:
 *   .lx-launcher  → small floating mic in the bottom-right (always visible)
 *   .lx-overlay   → full-screen JARVIS UI with rings, core orb, status text
 *   .minimized    → modifier on the wrapper that hides the overlay so the
 *                   launcher stays as the only visible UI while voice keeps
 *                   listening (used during navigation).
