• Desktop-first layout with strict grid constraints so the canvas never jumps while you work. Local state handles all loading and transition logic — Lottie animations swap in smoothly via isLoading gates, so you never stare at a frozen screen. • Frontend & Memory (FlutterFlow): the workspace canvas is fully decoupled from the upload pipeline. While the API processes your image, the UI stays responsive; state is kept local so you can reposition or zoom without waiting for the server round-trip. • Backend & Data Integrity (Supabase): processed images land in Supabase Object Storage. A tracking table logs every session event to keep storage clean and your high-res assets retrievable and secure. • API & Logic: images are sent to remove.bg as multipart payloads. A parameter pipeline captures the returned URL and locks your original aspect ratio before rendering — no squished outputs, no surprises.
