Refactored several things to make it easier to read (the HTML) and to format.

1. Changed text to form <p>text in here</p> instead of funky newlines before and after the tags.
2. Changed note at the top to a new class name, because it wasn’t a NEILGoal. CSS names make that easy, and it still shares the same CSS (for now). If we want to change it later, we can.
3. Exorcised the demons and funky characters in the convention table, and also cleaned up its CSS. It’s now easier to read in the text, in the HTML, and in the CSS. Yes - it’s not quite the same as the original, but only we’ll know that before long.
4. Eliminated the dead website reference in the blurb at the bottom of the table.
