/*
 * vsboat.app 公開ページのスタイル（2026-10-02 夜に作り直し）。HTML は src/site.ts、小さな動きは site.js。
 *
 * 方針（ui-ux-pro-max の推奨「3D & Hyperrealism ＋ Hero-Centric」を土台に、色と形はゲーム本体から取る）
 *   ・色: 夜の紺（ページ）、板の紺＋青の細線（pl_bar）、金（--c-accent #ffb840・淡金 #ffd682）、ロゴの橙 #ff7a00、白青の字。
 *         枠番の 6 色（白黒赤青黄緑。ゲームの .lane-N と同じ値）は枠番・帯など意味のある所だけに使う。
 *   ・形: ゲームの板と同じ「左上と右下の角を斜めに切った板＋内側の細線」（.plate）。丸い角の汎用カードは使わない。
 *   ・字: 見出しはゲームと同じ Noto Sans JP の太字（700/800/900。使う字だけを読む。site.ts の displayFontUrl）、本文は端末の字
 *         （iPhone・Mac はヒラギノ、Android は Noto Sans CJK）。数字もゲームと同じ太字＋斜体。見出しはゲームの「太字＋斜体」。
 *   ・動き: ヒーローの入り（1 回）と、遊び方の線の流れ（向きを示す）だけ。押せる物には押した手応え。動きを減らす設定では全部止める。
 *   ・暗い画面だけ（ゲームが夜の世界のため。color-scheme: dark）。
