/* ════════════════════════════════════════════════════════════════════ NEXUS PREFERENCES — visual layer -------------------------------------------------------------------- Three things live here: 1. Theme cross-fade — when [data-theme] changes, all CSS-variable driven colors fade smoothly instead of snapping. 2. Cinematic coin flip — the marquee gesture that fires when the user taps the masthead coin or switches advisor in Prefs. 3. Preferences bottom sheet — unified settings UI, opened from the utility tray's Prefs button. ════════════════════════════════════════════════════════════════════ */ /* ─── 1.
