ConstraintThe product problem
A frontend prototyping workspace for responsive layouts, reusable email templates, visual treatments, and isolated interaction experiments. The engineering challenge is to turn that scope into a legible system with explicit inputs, dependable workflow boundaries, and an outcome that can be inspected and maintained.
SystemThe architecture decision
The reviewed implementation routes input / action through domain & workflow logic, crosses external apis & platform services where required, and produces actionable result / automated outcome.
OutcomeThe operating result
UI and Email Prototypes is included as documented engineering work. Its source structure, technology stack, and functional flow are presented here even though no verified public deployment is currently available.
