/* =========================================================
   AMIX GAMES の共通メニュー（2026-11-12 本人：ヘッダーのリンクは PC もスマホもハンバーガーに・増やしていける）
   使うページ：index.html（トップ）・data.html（DATA CENTRAL）・award/2026/（AWARD）。動きは js/menu.js
   - 見た目はページの色に合わせる：各ページで --mn-bg / --mn-ink / --mn-dim / --mn-line / --mn-accent / --mn-f-big / --mn-f-k を上書きできる
   - ボタン（.amx-menu-btn）はヘッダーの中、パネル（.amx-menu）は body の直下（トップのヘッダーは mix-blend-mode がかかっているので、その外に置く）
