/*
 * Writing pages: /blog/, archives, search and the 404.

 * Layout only. Post cards, post rows, project cards, tiles, category chips and
 * pagination come from base.css. This file also loads on /blog/ next to
 * article.css, so every selector here uses its own class names.
 *
 * base.css resets ul[class] to margin 0 and padding 0 (specificity 0,1,1), so
 * lists that need spacing are written as ul.name.
