* CSS 先注入但所有模块默认关闭; 等页面原始 DOM 渲染后, 逐个模块探测原始尺寸, 成功后才打开该模块.
* 模块一旦探测成功就锁定, 避免后续 mutation 把已经放大的尺寸当成原始值再次相乘.
*
* 4) 探测结果缓存的是"原始尺寸", 不是放大后的尺寸.
* 缓存按模块保存; 命中缓存就直接设置 CSS 变量并启用模块, 未命中才延迟探测.
* 油猴菜单可清除缓存, 清除后刷新页面即可重新探测.
* 4) 不再缓存探测结果.
* Chaturbate 的列表宽度会随页面/窗口变化, 缓存旧尺寸容易污染新布局.
* 当前版本每次页面加载都重新探测; 油猴菜单只用于清除旧版本遗留的 localStorage 缓存.
*
* 5) 顶部"关注"弹窗的 FOLLOW_DROPDOWN_SHIFT_X 只是位置微调, 不属于缩略图倍率.
