/* The classic presentation of opencode native's site (classic/): a page about one screen across, a nav line of plain
   links, a column of text with the news beside it, Verdana for the text and Trebuchet for the headings, blue underlined
   links that turn purple once visited, thin grey rules; light and dark. The pages are made by occtools site changelog
   from the modern ones, so the modern classes that carry their content are made plain here. */
