/* Common parts of prism syntax highlighting CSS styles.

Pulled out of first couple selectors, plus edits:
 - no font size (we set ourselves)
 - no margin (we set ourselves)
 - line height 1.25
 - pulled out line highlighting (no change b/w styles)
 - pulled out diff highlighting (ditto)
 - diff-line-highlight CSS replaced w/ Eleventy variants that don't require
   another class (so diffs get line-highlighted by default).

/* Diff highlighting

Original selectors (from prism CSS) required additional `diff-highlight` class
to highlight line, which I don't want to figure out how to add to Eleventy's
Prism configuration. Simpler (current) selectors (from Eleventy) just
line-highlight all diffs.

Prism CSS: (downloaded from Prism website, see link above)
Eleventy CSS: https://www.11ty.dev/docs/plugins/syntaxhighlight/
