/* Note: Footer still has img in html, but if we change that too or keep it mixed. request said "header main logo". I will assume header only for now but text usually looks better consistent. I'll stick to header per request but if I change .logo class it might affect footer img wrapper. 
Actually seeing .logo img rule previously...
Let's remove .logo img rule and just style .logo.
Previous rule was:
.logo img { width: 120px; height: auto; }
I will remove that and add text styles.
But wait, the footer currently uses an image inside .logo. 
If I remove .logo img styles, the footer image might break or look wrong if I don't check.
Let's keep .logo img rule for the footer, but add .logo text styles for the header text.
