+# Forms + Validation Pattern
+
+Canonical patterns for server-rendered form workflows in Go web applications:
+
+- tabbed / mode-switched forms
+- datalist/autocomplete suggestions
+- inline validation messages
+- review / confirm step before submit
+- explicit reset and error handling states
+
+This pattern standardizes interaction flow and validation UX, not domain-specific field sets.
