/* Strides — blog

 * Loaded after site.css, so it inherits the tokens, nav, footer, pills and the
 * Home dialect's shape rule (cards 26, panels 18, cells 12). What it adds is a
 * reading experience: the serif carries the long sentences, figures sit on white
 * slabs, and charts keep one colour story: pink is hard, anaerobic work (the
 * app's speed hue), blue is aerobic work (the app's easy hue).
