- Resize/re-encode every uploaded image server-side (posts, avatars, stories,
shop products/logo, chat messages) via a shared sharp-based optimizer —
caps dimensions to what's actually displayed and re-compresses in place,
cutting a typical raw camera photo by ~90% with no visible quality loss
- Cap uploaded video resolution/bitrate (re-encode only when above 1280px/
~2.5Mbps) alongside the existing faststart step; apply faststart+cap to
story and chat videos too (previously stored completely raw)
- Add long-lived Cache-Control to all /storage static routes so clients stop
re-downloading unchanged media on every request
- Add gzip/brotli compression for JSON API responses (feed/explore/chat)
