/* style.css — 深海吞噬 · 黄铜潜水舷窗机台
 *
 * 排版红线（AGENTS.md §4 / 策划案 §4）：
 *   ① 拒绝“四角散落浮动按钮”：系统控制项全部收进舷窗顶部的窄黄铜状态条。
 *   ② 拒绝“右侧 SaaS 卡片堆”：所有 HUD 焊进舷窗框本身（左深度计 / 右贝壳心数 / 底罗盘 + 成长管）。
 *   ③ 拒绝“死白死黑大平铺”：整屏是沉浸式海水环境 —— 三段式渐变 + 斜射光柱 + 上浮气泡 +
 *      景深暗角，洋面是青绿，越深越蓝，但永远不做全屏暗蓝。
 *   ④ 桌面端舷窗居中（上限 1100px），左右与底部边缘不放任何操作按钮，为未来侧栏 / 通栏留白。
 *   ⑤ 移动端底部预留 ≥68px 安全缓冲，绝不让任何按钮贴底。
 *   ⑥ 所有动效在 prefers-reduced-motion 下瞬移降级。
