/* ================================================================
   首頁地景（2026-11 第二段 P1）＋文章全景（P2）—— 首頁與 /articles 共用，同一個文件裡軟導航
   兩種狀態：
   ・沒有 html.scene-on（無 JS、引擎沒起來）：首頁就是原本的內容流程（頭像、h1、副標、社群、專案、關於），
     地標連結是首屏下的一條連結列；canvas 不顯示。
   ・有 html.scene-on（head 內聯腳本在第一次繪製前就加上，所以不會位移）：整個視窗就是地景，
     地景就是操作介面。極簡外框（簽名、主題、暫停、標語、社群）都是 position:fixed 的真 DOM，疊在畫布上；
     舊的內容流程、導覽列、頁尾、手機底部導覽完全 display:none（退出鍵盤與讀屏流程），HTML 仍在，供後備。
   語言不變：線與點、不用色塊／陰影／模糊／漸層；圓角 ≤ 2px。
