Native GHL CRM Integration for Scaled Mockup Generation

As a GHL CRM agency owner,
I want a native integration that generates branded product mockups at scale using a PNG image URL from a custom field in each contact record.
so that I can automatically render high-quality visual assets for each contact, return them to the same contact ID, and optionally apply custom layout templates to display multiple mockup styles for email, web, or PURL campaigns.

Acceptance Criteria:

1. Integration reads a custom field (e.g., custom_logo_url) from each contact in GHL.

2. Sends PNG file to a mockup generation engine with template selection capability.

3. Returns one or more rendered mockup URLs per contact.

4. Saves output image links to mapped custom fields in the same contact record.

5. Supports layout templates showing single or multi-product styles per contact.

6. Runs in batch or trigger-based workflows inside GHL or connected via automation platform (e.g., n8n/Zapier/Make).
