/* 狀態玩家 v1.1「燈下」home page (spec /workspace/plans/healing/spec-design-v1.1-atami.md; mockup atami-v1-1, Bevis 2026-10-21).
   Only the home page loads this file; /privacy, /404 and /admin keep styles.css and tokens.css.
   Hard rules: viewport locked + touch-action: manipulation (Bevis v4.2); every field ≥ 16px; nowrap only on ≤ 8-character
   phrases (hero lines, choice labels; never the budget labels); no overflow-x: hidden on body (iOS ignores it);
   one breakpoint (960px) plus a < 360px tweak. Checked by scripts/layout-v4.mjs in WebKit + Chromium at 320/390/1440. */
