 `/earth-content` reuses the same single-screen tab container from [Settings.tsx](/home/ray/dev/linkong/planet/frontend/src/admin/pages/PlainResourcePages.tsx), but its ownership is separate from System Settings:
 
 - `TV Livestream` owns the Earth media-panel source configuration.
+- `Branding` owns Earth HUD brand assets. `Logo URL` and `Title Image URL` use inline upload controls inside the fields; the upload buttons keep the primary `TactileButton` style, and dropping an image onto the matching field shows a low-saturation drag reaction instead of the old global asset-picker toolbar.
 - `Boundary Precision` owns the Earth static boundary asset state: provider, low-precision fallback, high-precision manifest/PMTiles, source JSON, and build action.
 - `Base Map`, `Layer Resources`, `3D Assets`, and `News Anchor Strategy` are placeholders only. They show module status and do not invent fake APIs or fake data.

 `/earth-content` is under the console's Operations and Configuration group and owns resources used by the Earth frontend:

+- **Brand Assets**: manages the logo, title image, title text, subtitle, and description used by the Earth HUD. The `Logo URL` and `Title Image URL` fields each include their own Upload button, and image files can be dropped directly onto the matching field. After upload, the field receives the new asset URL; save the brand configuration to make the Earth page use it.
 - **About**: manages the About card shown in Earth settings, including logo, kicker, title, version, description, and metadata.
 - **TV Livestream**: manages sources shown in the Earth media panel.
 - **News Content**: browses news grouped by RSS source and manual group. RSS items remain read-only; manual groups support create, JSON import, edit, delete, and reprocess.

 1. `/collection-management?section=collector_credentials`: pick a collector and click the plug icon to test connectivity. Free collectors (e.g. open BGP) usually work right away; credential-bearing ones like `AISStream` or `BarentsWatch` need an API key / client secret first
 2. `/ai?section=integrations`: fill an LLM provider (e.g. `minimax` / `openai`), model, base URL, API key, and click the plug at the end of the base URL to test. WebSearch / OCR tools are optional
-3. `/datasources` or `/data`: check whether collectors have produced data. Use `/datasources -> Built-in Sources` for finite collectors: with no rows selected, click `Trigger All`; after selecting rows, the primary button becomes `Trigger Selected N`.
