/* app.css — 歌航日誌 demo PWA
   視覺方向 v0.7：復古航電儀表 × デンモク點陣（Flight Plan 駕駛艙的「做到底」版）
   材質系統——同一個艙內有五種不同的東西，不再是同一種卡片：
     .bezel      儀表本體（內凹、四角螺絲、玻璃反光）
     .ann-col    annunciator 警示燈鍵列（方形、燈亮=模式）
     .statusline CDU 綠磷光狀態行
     .panel      設備架卡（flight strip 的架子）
     .placard    貼在艙壁的說明銘板（平面、鉚釘虛線）
   讀數材質：DotGothic16 點陣字＝「點歌機遙控器的 LED 面板」，全站唯一最亮層。
   字體：Martian Mono（微標籤）+ Shippori Mincho B1（品牌）+ DotGothic16（讀數）+ 系統 CJK（內文）。 */
