/**
 * Horizontal top navigation bar for desktop shell.
 *
 * 🤖 **AI Agent Usage Notes (Zero-Raw-HTML Adherence)**:
 * - ⛔ NEVER use raw `<header>` tags or Tailwind flex rows for the main topbar.
 * - Always use `LuDesktopTopBar` placed inside the `topbar` slot of `LuDesktopShell`.
 * - Leverage `left`, `center`, and `right` slots for automatic alignment.
 *
 * @slots
 * - `left`: Left-aligned items (brand, menu toggle)
 * - `center`: Center-aligned items (search, tabs)
 * - `right`: Right-aligned items (actions, profile)
