Build a premium landing page for my book Dominium: Our Hidden Reality.

I need a Wix professional to design and build a premium landing page for my book Dominium: Our Hidden Reality. The website should have a refined editorial style, inspired by the book cover, using a dark blue textured background, elegant gold details, subtle decorative borders, and a cinematic, intellectual feel. English should be the default language, with a visible PT language switch in the top-right of the header.

The landing page should include:

Home / landing page

About the Book

Articles

Research

Videos

Contact

Buy the Book button

Learn More / About the Book button

Design requirements:

premium and sophisticated look

dark blue + gold palette

subtle ornamental frame inspired by the book cover

responsive for desktop and mobile

Clean typography and elegant spacing

ability to update content later inside Wix

Important:
I already have visual references and draft sketches for the homepage and inner pages. I want the designer to use these as inspiration and turn them into a polished, professional Wix website.
