# Functional Design Plan — react-frontend-app

## Unit Context
- **Unit**: `react-frontend-app` (single unit — Units Generation was skipped per the approved execution plan; this is the only unit of work for this feature)
- **Source**: `aidlc-docs/features/react-frontend/inception/requirements/requirements.md`

## Steps

- [x] Define the theme/color-token domain model (red default palette, purple alternate palette, shared token shape)
- [x] Define the static content domain model (nav links, hero copy, package/pricing cards, process steps, about/tech-stack content, contact info) sourced 1-to-1 from the reference designs
- [x] Define business rules for theme selection and persistence (default theme, switching behavior, persistence/fallback rules)
- [x] Define the frontend component hierarchy (Nav, Hero, PackagesSection/PackageCard, ProcessSection/Step, AboutSection, ContactSection, Footer, ThemeProvider/ThemeToggle)
- [x] Define props/state for each component and the user interaction flows (theme toggle click, anchor navigation, hover/focus states, mailto CTA)
- [x] Define the TanStack Router route structure (root layout route + index route housing the whole page for this iteration)
- [x] Define the TanStack Query integration point (provider placement + a placeholder query hook shape for future package/content data, backed by static data for now)
- [x] Generate context-appropriate clarification questions and store in a dedicated question file
- [x] Generate functional design artifacts: business-logic-model.md, business-rules.md, domain-entities.md, frontend-components.md
- [x] Present completion message and await approval
