/* ============================================================
   BOTTOM NAV — Luxsin X9 Controller (Mobile)
   Design: iOS/Android App-style bottom tab bar
   5 tabs — labels from locales/bottomNav, language = deviceState.language (同系统页)
   - 社区：移动端进入 /community 引导复制链接；桌面（lg+）点击仍 window.open 论坛
   - Active tab: cyan icon + top indicator bar
   - Inactive: muted icon + label
