/* ==========================================================================
   Luna Dimmer - Web Shell & Landing Rebuild (luna.css)
   --------------------------------------------------------------------------
   设计目标：
   1. 进入页面第一屏即呈现「左侧 1:1 Windows 原生微晶控制面板」；
   2. 整站统一为「月光 (Luna)」主题：深空夜色、月晕、星尘、琥珀月华；
   3. 严格复用既有交互契约（capsule-* / preset-pill / chip-2x-btn / ID 不变），
      只重构外壳、版式、材质与响应式，不破坏 simulator / modals / presets 逻辑。
   本文件最后加载，作为页面外观的最终权威。
