/*
  自社製品の紹介の共通部品（components/JishaProduct.tsx）の装い。2026-09-09指示【3】。

  中身は public/css/top.css（PC・.rt系）と public/css/sp.css（スマホ・.sp系）から、
  この部品が使う規則だけを **postcss で機械的に抜き出した**もの（手で書いた値は無い）。
  トップは今までどおり top.css / sp.css を読むので、トップの見た目は1画素も変わらない
  （切り出しの前後で画素比較して確認済み）。このファイルを読むのは /about だけ。

  2026-09-09指示【1】：この部品が使う文字を、部品自身が持つようにした。
  それまでは大きさ・行間・太さの一部をページの地から受け継いでいたため、
  トップ（.tone-world の行間1.85）と /about・/philosophy（.pv の行間）で値がずれていた
  （実測：見出し中の行間 トップ81.4px / 移した先63.8px、本文の行間 38px / 36px）。
  値はトップで実測したものをそのまま書いている。新しい値は作っていない。
  ヘッダー（app/shared.tsx）で同じ直し方をしたのと同じ考え方。
