What is Design Lab?
A temporary exploration mode for trying visual variants without touching the real project. Variants are disposable by design; only the chosen direction gets implemented.

Design Mixer Patterns
A library of composable visual directions (around 30 named patterns) the mixer combines per project. Patterns give the model a vocabulary beyond the default neutral look it reaches for otherwise.
Visual Editing
Clicking page elements in a live preview and asking the AI to refine text, spacing, or layout. It keeps non-developers in flow while the underlying code stays standard and editable.
Frontend Review / Critic Loop
Screenshot-only scoring out of ten with a two-iteration cap. The critic sees pixels, not code — which is exactly what users see too.
Guided Preflight
The multi-step setup wizard BYOB runs before generating code: refining the prompt, identifying features, proposing UX direction, and choosing data options. Planning first is what separates coherent apps from random screens.
Lucky Build (Autopilot)
The one-shot fast path that skips guided setup and generates directly from the prompt. Best for experiments and landing pages; guided preflight wins for anything with data or auth.
Pass-1 Build
The uninterruptible first generation surface: styles, layout, page, components, then validation. Letting pass one finish prevents half-built states that later edits have to repair.
