Gen Z Gym Companion

A mobile-first Next.js experience that turns any beginner PDF into a vibrant, animated workout tracker. The current MVP simulates the "AI" backend with a mock JSON response but preserves the full upload flow so we can swap in a real service later.

Stack

• Next.js 16 (App Router) + React 19
• Tailwind CSS v4 + shadcn/ui components + lucide-react icons
• Framer Motion for page/component animations
• date-fns for streaks, timestamps, and friendly dates

Architecture

• app/page.tsx only decides between onboarding and dashboard states via useWorkoutStore.
• app/lib/data.ts hosts the mock AI JSON; swap with a real API response without touching UI code.
• app/lib/hooks.ts owns localStorage hydration, streak resets, and the toggleComplete checklist logic.
• app/components/* break the UI into focused pieces (Onboarding, Dashboard, StatsGrid, WorkoutList, ExerciseCard).

Features

• Two-step onboarding (name + PDF upload) with a simulated AI parsing delay.
• Neon-inspired dashboard header, stat grid, and accordion-based workout list with animated checkboxes.
• Daily progress + streak tracking, with completions auto-clearing when the calendar date changes.
• Rest-day detection that swaps the workout list for a playful recovery card.

Run It Locally

npm install
npm run dev

Open http://localhost:3000 on a phone or narrow browser window for the intended experience. To reset the experience, clear localStorage (key: gym-app-store) or use the helper inside useWorkoutStore.*** End Patch
