/* UGO — the floating button, the mobile menu and the "Ask UGO" chat panel (js/ugo-fab.js builds them).
 *
 * The button is green and sits at the bottom right of every public page:
 *   phone in a browser   -> hamburger at 50% opacity; it opens the menu (which has the AI assistant in it)
 *   desktop              -> AI sparkle at full opacity; it opens the chat panel
 *   installed app (PWA)  -> AI sparkle only, on every screen size
 * Layers: the product pages' bottom bar is z-index 800 and its "More" sheet 815-820; the button is 810; the menu and the chat panel
 * sit above everything but toasts while they are open. Light or dark follows the page (js/ugo-fab.js sets data-ugo-theme). */
