  • Server: resize uploads to max 1200px + generate 600px _thumb.jpg
  • Server: cache /uploads with max-age=1y immutable headers
  • Client: CatCard uses _thumb.jpg in feed (fallback to full on error)
  • Client: first 3 feed cards load eagerly (LCP), rest lazy + decoding=async
  • Client: loading placeholder bg while image fetches
  • Migration: server/src/scripts/gen-thumbs.ts for existing images
