在 user 记录上新增播放器音量、弹幕开关、透明度、字号、显示区域、合并偏好、自定义弹幕源以及 dandanplay 应用凭据字段，并提供 PUT /danmaku/settings 局部更新接口，带取值校验。 返回脱敏后的完整渲染配置，绝不回传应用密钥，仅在响应中标记密钥是否已配置。 结果缓存键加入用户 ID 与凭据指纹，避免不同用户或凭据串用缓存；旧版实例级设置仅作为未登录与迁移期的回退。

/**

* JASSUB probes color space with `new VideoFrame(video)` during construct.
|
|
* Direct-play 302s to a CDN / remote Emby taint <video>, and Chrome throws
|
|
* SecurityError. Overlay rendering uses requestVideoFrameCallback metadata,
|
|
* not pixels, so hide VideoFrame for the sync constructor call.
|
|
*
|
|
* ponytail: skips color-space matching for all ASS playback, not only tainted
|
|
* sources. 302 completes after construct, so we cannot probe currentSrc first.
|
|
* Upgrade: canvas-only JASSUB driven by rVFC metadata when the element taints.
