/*****************************************************
TYPOGRAPHY

Everything that styles running prose and the things embedded in it. Fonts are
imported in base.css.

Sections, in order: body type and headings, tables, code blocks, syntax
highlighting, footnotes, blockquotes, pullquotes, alerts.

Loads:    every page
Used by:  typography/alert.html, typography/pullquote.html, and every page of
          Markdown — most of this file styles bare elements, not classes
Needs:    base.css tokens (--text-*, --font-*, --bg-code*, --spacing-*)
Not here: the `.container` grid that gives prose its measure (base.css)
