Build a simple, clean lead/contact form for a marketing business.

The page should be modern, minimal, and professional.

Include these fields:

Name
Email
Question
Feedback

Use a clear heading such as:
Have a Question?

Add a short supporting line like:
Send us your question or feedback and we'll get back to you.

WEBHOOK
When the form is submitted, send the data as a POST request to the n8n webhook URL.
The data should be sent as JSON with keys: name, email, question, feedback.
Do not ask me to paste the webhook URL into the page or source code.

SUBMISSION STATES
While submitting, change the button text to something like:
Sending...

After a successful submission, show:
Thanks! Your message has been received.

If the webhook request fails, show a simple friendly error:
Something went wrong. Please try again.

VALIDATION
Require Name, Email, and Question. Feedback is optional.
Validate the email format.

Make it responsive for desktop and mobile.

Do not add unnecessary sections, navigation, pricing, testimonials, or other marketing content.

The main purpose of this project is to demonstrate sending form data from Lovable to an n8n webhook.

IMPORTANT
Do not hard-code any webhook URL.
Reference the N8N_WEBHOOK_URL secret/config value when sending the form submission.
The actual secret will be added manually later in Lovable Cloud, under Secrets.
