/* ヲタログの見た目
   ==================================================================
   ここは店ではなく**台帳**です。売り買いする場所ではなく、
   「何があるか」「自分は持っているか」「いくらが相場か」を調べて
   記録する道具です。通販サイトの作り（大きな赤い値段、買うボタン、
   派手な帯）はそのまま当てはまりません。

   使う人がやりたいことは3つ。見た目はこの順に合わせます。

     1. 推しのグッズを探す   → 写真が見やすく、キャラクターから辿れる
     2. 持っているか確かめる → 持ち物の印が流し見で分かる
     3. 相場を知る           → 数字が桁で揃い、比べやすい

   作りの方針
     - 細い罫と余白で整える。影と丸みは最小限。台帳らしく静かに。
     - 数字は等幅で揃える（font-variant-numeric: tabular-nums）。
     - 色は1色だけ差す。選んでいるものと、持ち物の印に使う。

   並び
     1. 下地      色・字・間隔の決めごと
     2. 骨格      ヘッダー、幅、余白
     3. 部品      ボタン、チップ、札、表、選択欄
     4. 画面      トップ、カタログ、商品、コレクション
     5. 狭い画面  スマートフォン向けの差し替え
