   JEWEL-UI-1031 · ORYZO 总纲（2026-10-31 落地）：
   - 暖暗底 #100904（非纯黑）、暖米文字 #ffedd7（非纯白）、
     次要 #6c5f51、边框/分隔线 #40372e、抬起面 #382416
   - 每幕 100vh（100svh 兼容移动端工具栏，vh 兜底）
   - 画面居中，内容两侧 18px flank
   - 字阶：展示 51 / 标题 41 / 正文 29，字重 400；UI 全大写、字重 500
   - 圆角：卡片 12 / 幽灵 22.5 / 填充 pill 36 / 输入 0；不用 9999px
   - 分隔线 1px 虚线 #40372e
   - 正文始终左对齐
   - 珠宝金色只留在已批位置（kicker、按钮、展品卡描边），不扩成 CTA 填充
   - 中文行高：ORYZO 的 0.9 / 1.26 是拉丁值，中文按可读性取 1.05 / 1.5
