Flask App Builder

Echo's primary skill for building and maintaining Liberty-Emporium Flask apps.

Stack

All apps share the same pattern:

• Backend: Python 3.11 + Flask + SQLite (via Railway volume at /data)
• Auth: bcrypt passwords + Flask sessions + CSRF protection
• Frontend: Jinja2 templates, Inter font, dark navy/indigo color system
• Hosting: Railway (auto-deploy on git push)
• AI: OpenRouter API (model picker in settings)
• Payments: Stripe (optional, in requirements)

App Registry

See references/app-registry.md for all app URLs, credentials, repo names, and Railway deployment IDs.
