/**
 * bottom-nav.css — single source of truth for the mobile bottom navigation.
 *
 * Loaded on every page that renders BottomNav (discover, category pages,
 * livefeed, portfolio, orders, watchlist, account). Consolidates what used to
 * be split between mobile.css (base bar) and discover-mobile.css (icons + bonds
 * popup), and adds the "you" account hub.
 *
 * Layout: discover · bonds▾ · livefeed · portfolio · you▾
 *   - bonds▾ opens a category sheet (government / corporate / gold / tax-free)
 *   - you▾   opens an account sheet (orders / watchlist / account)
