Headers were butting up against previous paragraphs too closely. Changed rendered markdown header selectors from :where() to direct element selectors to increase CSS specificity and beat Tailwind prose defaults. Bumped margin-top from 1.15rem to 1.75rem. Also added top margins to MDXEditor headers (h1: 1.4em, h2: 1.3em, h3: 1.2em) which previously had none.
