Build a gamified daily challenge web app for children

I need a full-stack web application built for a South African educational startup targeting parents and children aged 6–13.

The platform is a **subscription-based daily challenge system** where children compete on leaderboards by completing short, timed activities across multiple subjects.

**Target users:** Parents (paying subscribers) and their children (users)

**Core monetisation:** Monthly subscription (R120–R150 ZAR)

---

## What the App Must Do (High Level)

### For Parents:
- Sign up / log in (email or Google)
- Add multiple child profiles (name, grade, avatar)
- Subscribe via Stripe (14-day free trial then monthly)
- View each child's progress (weekly scores, strengths/weaknesses)
- See leaderboards (by suburb, school, friend groups)
- Download printable certificates and progress reports

### For Children:
- Select their profile and see "today's challenge pack"
- Complete 5–7 short activities (maths minute, word jumble, comprehension, colouring upload, SA quiz, etc.)
- Earn points instantly
- View leaderboards (with podium for top 3)
- Earn streak badges and digital rewards

### For Admin (you will build this for me):
- Question bank manager (add/edit/delete questions by grade and category)
- View subscribers and revenue
- Manage school codes and suburbs

---

## Key Technical Requirements

**Stack preference:** React + Supabase + Stripe + Tailwind CSS
**Hosting:** Vercel or Netlify ready
**Payments:** Stripe (ZAR currency, monthly subscriptions)
**File uploads:** For children's drawings/colouring pages (store in Supabase Storage)
**Daily pack generation:** Automated cron job (Supabase edge function) that assembles unique daily packs from question banks

---

## CRITICAL: UI/UX Requirements

This is a **children's platform**. The UI must be:

- **Bright, playful, colourful** – no corporate grey/blue SaaS styling
- **Rounded corners everywhere** (24px+ border-radius)
- **Large touch targets** (buttons 56px+ height)
- **Emoji-rich** (trophies, stars, animals, etc.)
- **Animated** (confetti on completion, bounce effects, hover scaling)
- **Mobile-first** (tablet and phone primary use)
- **Character-friendly** – space for a mascot (I can add illustrations later)

**I will reject proposals if your portfolio shows only boring admin dashboards or generic corporate apps.**
