v1.10.2: 侧边栏「没有模型？注册即送额度」移到 LLM 配置正上方

- 订单状态区新增「你的卡密」展示区，拿到 card_key 立刻显示（不等激活结果）
- 自动激活失败时给出手动激活路径（卡密+侧边栏步骤+订单号）
- paid 但无卡密时显示发卡进度，90s 后提示权益不丢失可凭订单号补发
- 卡密一键复制（clipboard API → execCommand 降级）

+## v1.10.2 · 2026-10-20
+
+### 🔧 调整
+- 侧边栏「🤖 没有模型？注册即送额度」**移到 LLM 配置正上方**——原先它卡在授权区和评论记录之间，和 LLM 之间隔着一大块，现在配模型时一眼就能看到注册送额度的入口
+
+---
+
+## v1.10.1 · 2026-10-20
+
+### ✨ 新功能
+- **支付成功后立刻显示卡密**：只要服务端发出卡，订单状态区马上出现独立的「你的卡密」展示区（大号等宽字体 + 一键复制），**不等自动激活结果**——自动激活失败时用户手里也有码，回侧边栏粘贴即可激活
+- **「已支付但还没发卡」的明确状态**：订单已是 `paid` 却还没拿到卡密时显示「已支付，正在为你发卡」，超过 90 秒改为「**权益不会丢失**，可凭订单号联系客服补发」，不再无限转在「等待支付中」
+- 卡密一键复制，剪贴板 API 无权限时自动降级 `execCommand`
+
+### 🔧 调整
+- 激活失败时给出可执行路径（卡密展示 + 侧边栏操作步骤 + 订单号），不再只报一句错误
+- 卡密展示区用 B站蓝虚线框独立成块，`user-select: all` 便于长按全选
+
+---
+
+## v1.10.0 · 2026-10-20
+
+### ✨ 新功能
+- **新增「当前商品选择页」`buy.html`**：侧边栏「购买授权 →」不再跳外部授权站点，改为在插件内打开新标签页，实时展示授权系统**当前在售的商品**（名称 / 价格 / 时长），选中后进入下一步
+- **三步购买流程**：选当前商品 → 选支付方式（支付宝 / 微信）→ 完成支付后**自动发卡并激活本机**，全程无需手动输入卡密
+- **后台订单轮询**（新增 `alarms` 权限）：购买页或侧边栏被关掉，后台仍继续轮询，支付成功后自动完成激活；超过 12 小时未完成的订单自动停止轮询，不会永久占用
+- 订单状态区分「等待支付 / 支付成功 / 激活失败 / 超时」，等待时实时显示已等待秒数，超时给出订单号供人工补发
+
+### 🔧 调整
+- 购买入口从 `https://auth.88531.cn` 改为插件内置页 `buy.html`（B站蓝 `#00A1D6` 配色），页脚保留官网 `dl.88531.cn/bili.html`、GitHub、Telegram 入口
+- 商品列表由授权系统实时下发：显示的就是当前在售商品，下架商品不会出现在页面上
+- 本版本只调用授权系统的公开读写接口，**不改动服务端任何配置**
+
+---
+
+## v1.9.0 · 2026-10-14
+
+### ✨ 新功能
+- **试用策略改为 3 天 / 30 条评论，任一先到即止**：试用时长从 1 天延长到 3 天，同时设置 30 条评论上限。额度用完或时间到期，哪个先到就停哪个
+- **价值时刻提示**：每批跑完直接显示「本批 N 条已发布，平均间隔 X 秒」，并同步刷新顶部横幅的剩余条数——让用户亲眼看到成果的同时看到还剩多少
+- **到期后 24 小时折扣窗口**：试用结束后 24 小时内，面板横幅显示「24 小时内购买享 8 折」并倒计时；窗口关闭后恢复原价
+- **过期只锁评论**：试用到期后仅锁定自动评论，搜索视频、AI 生成文案、下载当前页视频继续可用，用户不会被彻底踢走
+
+### 🔧 调整
+- 顶部横幅文案：试用中显示「剩余 X 时 · 还可评论 N 条」；额度用完与时间到期分别给出不同提示
+- 试用计数只在未授权状态下累加，已激活用户不受任何影响
+- 官网与 README 同步更新试用规则、折扣窗口说明
