* 主题内容注入点：在标准位置注入广告/统计/临时链接等 HTML。

|
|
* 注入点（Blade @stack，主题视图内置）：
|
|
* head / header / sidebar_top / sidebar_bottom / content_top / content_bottom
|
|
* post_content_top / post_content_bottom / footer / body_end
|
|
*
|
|
* 特性：
|
|
* 1. 同一位置可配置「多条」注入块（后台主题注入页管理），按 sort 顺序渲染
|
|
* 2. 每条可启停
|
|
* 3. 插件可通过 filter `theme.inject.{point}` 追加
|
|
* 4. 主题变量（stylevar）：theme('var', 'key') 引用任意键值 HTML
