  site-chrome-lp.css — 追憶のきらめき サイト共通の「ヘッダー(ロゴ＋ハンバーガー)・ドロワー・フッター」の見た目。
  ★2026-09-14: LP(index.html)の inline CSS から【そのままの順序で】切り出した(1 バイトも変えていない)。LP と /live/ が同じ 1 本を読む。
  ★LP では元の inline 定義と同じ位置(<style> を一度閉じて挟む)で読む=前後の同じ詳細度の勝ち負けを変えないため
    (吹き出し CSS の切り出しで 11 か所ずれた実測あり: docs/handoff/PLAN-live-ranking-components-2026-09-14.md)。
  ★使う側が用意するもの: .shell / .visually-hidden / CSS 変数 --text-secondary --gold --shell-pad --lp-yoz-mist --lp-yoz-petal-mid。
  マークアップと開閉 JS は assets/js/site-chrome-lp.js が生成する。
