+## Ejemplo
+
+```tsx
+<Input placeholder="Email" type="email" />
+<InputGroup>
+  <InputIcon position="start"><SearchIcon /></InputIcon>
+  <Input placeholder="Buscar..." />
+</InputGroup>
+```
+
+## Notas
+
+Exporta Input, InputGroup e InputIcon. Usa Mantine TextInput internamente. InputGroup e InputIcon se mantienen como wrappers de compatibilidad — para nuevos usos preferir leftSection/rightSection de Mantine TextInput directamente.
