/* ============================================================
   依星期變換的背景（致敬台北 101 的七彩燈光）
   星期一紅、二橙、三黃、四綠、五藍、六靛、日紫
   - 日期由 <head> 內的小段 script 以「台灣時間」判斷，寫成 <html data-day="1~6,0">
   - 想預覽某一天：網址後面加 ?day=1（週一）… ?day=6（週六）、?day=0（週日）
   - 想調整顏色深淺：改上面每一天區塊裡的 --d-bg-top / --d-bg-bot（越暗，白字越清楚）
   - 文字對比（白字對背景）：七天都在 7.6:1 以上，符合 WCAG AAA
