HTML to Business Website

I already have the core HTML for a corporate-style site, but it isn’t quite production-ready. The code needs a round of layout adjustments and, most importantly, my company logo has to appear cleanly in both the header and the footer across every page.

Here’s what I need from you:
• Refactor the existing HTML/CSS so the overall layout matches a polished corporate look (spacing, alignment, font consistency, responsive behaviour).
• Embed the supplied logo file into the global header and footer templates, ensuring it scales well on desktop, tablet, and mobile.
• Optimise any supporting assets or stylesheets you touch so the pages load fast and stay standards-compliant.
• Hand back the updated source files plus a brief note on the changes, so I can maintain them in-house later.

All pages should render identically in the latest Chrome, Firefox, Safari, and Edge. Once everything is tightened up, a quick walk-through of what you changed will close the project.
