在既有克制视觉语言（单一蓝 · 无渐变 · 1px 边线分隔 · Outfit 数字/西文）
内做精并补足信息量,所有色值走 tokens,check-code 闸通过:

- Hero 加资质 eyebrow（五端一套账号·时长永不过期）
- 指标带 3→4 项（首字延迟 / 5 端 / 3 分钟每天 / 时长不过期）
- 特性 3→6（新增 上滑取消 / 浮层不抢焦点 / 中英混说）
- 新增「使用场景」4 卡（写作·消息·代码·会议,各带你说→上屏示例 + 3× 提速角标）
- 新增「隐私与信任」深色带 4 点（只按住时录音 / 音频用完即弃 / 只往光标写 / 透明计费）
- 平台区改信息卡片（桌面/手机/平板,各附一句能力说明）
- 定价卡加权益清单 + 热门档强调
- 新增「常见问题」8 条 details 手风琴（联网/隐私/准确率/跨端时长/兼容/额度/对比/方言）
- 页脚扩为四栏（产品·购买·支持 + 品牌介绍 + 运营主体）
- 双主题 + 移动窄屏截图验收通过；reduced-motion / focus-visible 已覆盖
