+# Apple Form
+
+Apple-style 3-field step-by-step customer form with FastAPI backend.
+
+## Frontend
+
+Single-file HTML (`index.html`) — zero dependencies, native system fonts.
+
+- 3-step wizard: Email → Name → Domain
+- Apple design system: `#f5f5f7` backgrounds, Apple Blue `#0071e3` accent, SF Pro typography
+- Slide animations between steps, step-dot progress indicator
+- SVG checkmark draw animation on success
+- POSTs to the backend at `http://192.168.1.121:8080/api/submit`
+
+### Open directly
+
+```bash
+firefox index.html
+```
+
+Or serve from an HTTP server:
+
+```bash
+python3 -m http.server 8000
+```
