/* public/theme/portal.css
 * where : 入口（matome.biz）だけで読む（src/app/portal/page.tsx）。common.css は読まないので、ここだけで完結させる。
 * what  : 入口の絵とサービス名、20サイトのカード一覧。カードは各サイトの色（--p 主役 / --d 深い色 / --a 差し色）と
 *         ロゴの書体（--f / --fw）をカードの style で受け取る。
 * why   : 広告を置かないページなので、ここだけは1つの作りで PC とスマホの両方に合わせる（幅で列の数が変わる）。
