Apply Custom Design to Odoo -- 2

I already have a complete six-page website design and now need it reproduced inside Odoo 18 with pixel-perfect fidelity. The work revolves around building or extending a theme so every layout, font, colour and interaction from my mock-ups appears exactly the same once deployed.

The site runs on the Odoo e-commerce module, so the new theme must fully support the product catalog and shopping cart flows out of the box; payment gateway screens can stay on Odoo’s default styling for the moment, but the code should remain flexible enough for future tweaks.

Deliverables
• Custom Odoo 18 theme implementing all six pages.
• Styled product catalog and cart views wired to existing e-commerce logic.
• All source files plus a brief install/update guide.
