shubham-landge/strengthlab-gym-management — reverse-engineered prompt

Build me a local web app for managing a gym called StrengthLab. I want staff to open it on the gym computer and other devices on the same WiFi, with simple logins for admin, owner, accountant, trainers, and members.

The admin area should manage members, trainers, equipment, attendance, payments, reports, and announcements. Members should have their own dashboard showing subscription status, BMI, assigned trainer, payment history, workout plan, and diet plan. When a new member is added, the app should create sensible workout and diet plans from their goals, health info, body stats, and whether they picked premium service.

Add WhatsApp ready message links for broadcasts, payment reminders, payment received messages, and progress updates. Payments should get automatic due reminders and renewal reminders without spamming the same person all day. Diet plans should be downloadable as PDFs.

Use a simple local database that seeds itself on first run. If AI keys are added, let admins draft premium workout and diet plans with AI, but keep a local fallback if AI fails.
