   OSCF 公式サイト v3（ロゴ基調）
   レイアウト: 12カラム・左揃えの編集的な組版。節の名前は左3カラム（PCでは追従）、本文は右9カラム。

   色の役割（ロゴキット 70_Outputs/oscf-logo-kit の5色から。役割を固定して、ページに散らさない）
   役割          トークン        値        使う場所
   ------------  --------------  --------  ------------------------------------------------------------
   地            --paper         #FAFAF8   ページの地。ロゴの白地に合わせ、黄みを抑えた白
   面            --paper-2       #F2F1EE   節の切り替え（tint の節）
   文字・構造    --ink           #15191B   ロゴの墨。本文・見出し・図の線・罫（地の上で 16.9:1）
                                           墨の面（白文字）は、財団が担う範囲を示す1か所だけ（事業紹介の役割の表の中央）
   補足の文字    --ink-2         #3E4448   導入文・説明（9.5:1）
                 --ink-3         #5D6368   ラベル・日付（地で 5.8:1、面で 5.4:1）
   主役          --red           #E51A46   ロゴのレッド。次の3つだけに使う
                                             1 行動: 主ボタンの地（白文字 4.6:1）、お問い合わせの帯
                                             2 現在地: ナビ・ページ内ナビの下線
                                             3 強調: 図の主線と動く点（学び続ける人）、各節で1点だけの強調
   赤い文字      --red-ink       #B8103A   赤で文字を書くとき・主ボタンの hover（地で 6.3:1、面で 5.9:1）
                                           #E51A46 は地の上の文字だと 4.4:1 で AA に届かないため、文字には使わない
                 --red-wash      #FBE4E9   文字を選択したときの地だけ
   基準          --blue          #2075B4   ロゴのブルー。図の中の「組織の基準」（目盛りと、基準を通る点）だけ
                 --blue-ink      #1C65A0   基準を説明する文字（地で 5.9:1）
   ロゴだけ      --yellow        #F0BA1D   ロゴの中だけ。部品・文字・印には使わない
                 --green         #3A9629   ロゴの中だけ（パネルをつなぐ線）
   濃い地        --night         #15191B   フッター（墨）。文字は --on-night（15.8:1）と --on-night-2（7.9:1）

   書体: 和文＝Noto Sans JP（ロゴの和文名と同じ）、欧文・数字＝Inter（ロゴの英文名と同じ）。
         見出しもゴシック（赤×明朝は日本AI大賞のトーンと重なるため使わない）。
         見出しの太さは 600〜650（ロゴの和文名は 650）。palt は見出しだけにかける。
