/* 公司首頁的樣式。版型沿用支持網站（MarkuWorld/MarkuSupport/wwwroot/css/support.css）的頁首、頁尾、字級與品牌卡，
   外觀照設計說明 marku/products/reader-support/design/README.md 的「公司首頁」。
   只用系統字、不從外部載入任何東西；頁面跟系統的淺深色，兩張品牌卡用各自品牌的顏色。
   主要文字、連結與按鈕用碼庫色票的墨（深色模式用霧白），色票見 marku/brands/marku/README.md「色彩」。
   頁首、頁尾與色彩代號全站共用；條款三頁的長文版面另外寫在 legal.css。 */
