We are developing a video creation app for Anna. We plan to provide a preset library that helps users choose camera movements, visual styles, compositions, effects, and audio treatments.

This library may contain hundreds of:

- Preset thumbnails
- 3–5 second preview videos
- Audio samples
- Reference images
- Related prompt templates and model parameters

Preset JSON, prompt templates, and a small number of icons can live in the App bundle. However, a large media library should not be:

- Bundled into every Executa binary
- Duplicated into each user’s APS storage
- Tied to short-lived upload or generation URLs
- Republished with the entire App whenever one asset changes

APS is a good fit for user-uploaded assets and generated videos, but not for a developer-owned preset library shared by every user.

We would therefore like Anna to provide CDN-backed, App-level shared asset hosting, for example:

```auto
developer.assets.upload
developer.assets.list
developer.assets.delete
developer.assets.getUrl

```

Ideally, it would support:

- Assets associated with an App and version
- Shared access for all users without per-user duplication
- Stable or content-hashed URLs
- Images, audio, MP4, and WebM
- HTTP Range Requests for video streaming
- CDN edge caching
- Automatic CSP and CORS configuration for App iframes
- Asset metadata and manifests
- Updating the asset library independently from the Executa binary
- Reasonable storage and bandwidth quotas

Our intended architecture is:

```auto
App bundle
└── presets.json
    ├── preset name
    ├── prompt template
    ├── model parameters
    ├── thumbnail_url
    └── preview_video_url

Anna App Assets CDN
├── thumbnails/*.webp
├── previews/*.webm
├── previews/*.mp4
├── audio/*.mp3
└── references/*.jpg

APS
├── user-uploaded assets
└── user-generated videos

Executa
└── video processing and provider integration code

```

Could the Anna team clarify:

1. Is the current App bundle hosting intended for storing and lazily loading hundreds of video preset assets?
2. If not, is developer-owned, App-level public asset hosting or a CDN Asset API planned?
3. Until such a feature is available, does Anna officially recommend using an external R2/S3/CDN configured through `external_origins` and `csp_overrides`?
