Redundancy Removal: #body2 relative not used

Not sure what this was for, possibly from when <h1> was along the top, but
it doesn't seem to be doing anything.
Refactoring: All zeroes are the same
Redundancy Removal: <h1> relative

The :before ♡ is fine without it.
Refactoring: Better organized colours

Always set foreground colours (including for links in various states)
right after background colours. This avoids the home page being a special
case.

Merge <h1> and #nav link settings under #header, since they are for the
same reason.
Refactoring: Everything on home page is script

Don't treat <strong> as being special.
Commenting: More logical directive order

Will be easier to comment like this.

Committed separately from the comments so it's easier to see it's exactly
the same content but in a different order (and that adding comments
doesn't change anything else).
Refactoring: Simpler table top gap

Rather than picking out the top table row as special to avoid adding
padding to it because there's already margin on the table itself, simply
don't add that space to the top of the table.

Then the first row is no longer special: all rows have padding-top.
Comments: Everything commented
