## 🌟 Core Architecture & Engineering Highlights

Seal combines the power of desktop-class command-line media downloading tools with a modern, reactive mobile frontend.

### Embedded yt-dlp Backend & FFmpeg Media Muxing Pipeline
Seal bundles an optimized, mobile-compiled build of the industry-standard **yt-dlp engine** alongside **FFmpeg**. When downloading multi-stream video content, yt-dlp downloads high-bitrate video and lossless audio streams in parallel, while mobile FFmpeg muxes them on the fly into standard MP4, WebM, or MKV containers without requiring re-encoding or quality loss.

### Custom Command-Line Arguments & Power-User Templates
For advanced archivists, Seal provides an unrestricted **Custom Command-Line Injector**. Users can inject raw yt-dlp flags (such as `--extract-audio --audio-format flac`, `--sponsorblock-remove all`, or `--cookies-from-browser`), saving custom command templates for rapid single-tap execution.

### High-Resolution Metadata Muxer & Subtitle Embedding
Seal automatically extracts high-resolution 1000x1000 square cover art and metadata tags (Title, Artist, Album, Year, Track Number), embedding them directly into downloaded MP3, M4A, or FLAC audio files. It natively downloads and embeds multi-language subtitles in standard SRT or VTT formats.

### 4. Browser Cookies Ingestion for Private Videos
