/*
  Tiny Wonders — 「どうぶつ絵とき帖」= 昭和〜平成の図鑑・博物画をモチーフにした
  トリビア・エンタメメディアのデザイン(2026-09-06、軸再定義に伴うフル再デザイン)。

  配色の根拠: 経年した図鑑の紙(マスタード寄りのパーチメント)を土台に、
  カテゴリごとに標本ラベル色を持たせる「図鑑の分類色」構造を採用。
  雑学=発見(森の緑)/ざんねん=愛嬌(素焼きのテラコッタ)を色で区別し、
  ボタン等の共通UIは書物の金箔押しを思わせるマスタードで統一する。
  カードは現代的なソフトシャドウをやめ、図版に貼るラベルのような
  細い二重罫線(hairline)で「標本・図版」らしさを出す。
