The praxis theme has two CSS files in css/: style.css (2000 lines, the
actual stylesheet loaded by the Twig template via assets.add('theme://
css/style.css')) and _style.css (1928 lines, a partial/backup variant
with different values). I had been copying _style.css all along —
wrong file. style.css has the correct line-heights (h1 34px, h2 28px
vs the partial's 24/24), an extra .text-bg rule, and the proper media
breakpoints. That's why paragraph spacing kept diverging from live no
matter what I touched in the body block — the differences were in the
heading rules and elsewhere in the file. Replace praxis.css with the
real source.
