[FEATURE] File Size Validation

Problem

No validation for file sizes before uploading. Large files can cause browser crashes or storage issues.
Users can accidentally upload huge files, causing performance problems.

Solution

Pre-upload Validation with Hard Limits

• Validate file size before processing starts
• Reject files exceeding configured limits immediately
• Show clear error messages with file size info
• Different limits for images, videos, and audio
• Pros: Simple, prevents issues early
• Cons: May be too restrictive for some use cases

Alternative

Approach 1: Soft Limits with Warnings

• Allow uploads but show warnings for large files
• Provide "Continue anyway" option
• Track large files separately
• Pros: Flexible, user-friendly
• Cons: Users might ignore warnings

Approach 2: Progressive Upload with Chunking

• Split large files into chunks
• Upload chunks progressively
• Validate chunk size
• Pros: Handles very large files, better UX
• Cons: Complex implementation, requires chunking logic

Implementation Details:

• Add file size limits (configurable, with sensible defaults)
  • Images: 50MB default, configurable up to 200MB
  • Videos: 500MB default, configurable up to 2GB
  • Audio: 100MB default, configurable up to 500MB
• Show warnings for large files with file size info
• Provide file size information in media panel (already have file.size)
• Option to compress images before adding (using browser-image-compression or similar)
• Check available quota using navigator.storage.estimate()
• Display storage usage indicator

Anything else?

No response

Empieza por localizar el panel de medios y el uso existente de file.size. Decide qué enfoque de validación y qué límites de tipo de archivo están dentro del alcance, y determina después cómo deben interactuar las advertencias, las comprobaciones de cuota, la compresión o el chunking. Done debe incluir límites configurables, comentarios claros relacionados con el tamaño y un comportamiento definido para las cargas demasiado grandes.
