As a restaurant manager, I want a dead-simple, tablet-friendly admin page where I can sign into my location, enter today’s soup and special, attach a photo, and tap Publish so it appears on my location’s page on the company website within seconds—no IT help needed. The UI should be mobile-first with large, touchable controls and clear success/error feedback. Each location must have its own secure login and only access its own data. Build the front end with Svelte and use Firebase (Firestore for real-time updates and Storage for images) on the back end.
