Could you build this?
Partial Rebuilding standard UI views with CSS and TypeScript is vibe-codeable, but accurately simulating 24 functional apps, file systems, camera pipelines, and ported WASM engines (like Doom) represents an enormous software engineering surface area.
What it would actually take: The architecture is a complex TypeScript single-page application orchestrating virtual window managers, pseudo-multitasking state, simulated local storage file systems, and WebAssembly modules (e.g., compiled Doom C code). The primary barrier is the massive engineering effort to achieve pixel-perfect skeuomorphic rendering, gesture responsiveness (slide to unlock, spring physics), and faithful emulation of iOS 4 system services. It requires strong graphics, physics, and client-side systems engineering.

Same idea, different domain
Nobody's really built a vertical saas tool for Insurance yet.
