docs(fonts[css]): fix variable specificity — use body instead of :root

tony · tony · commit 3bca8c5fd27c · 2026-03-13T17:45:03.000-05:00
why: Furo sets --font-stack on body, which overrides :root via direct
declaration. Our fonts.css loaded but never rendered.
what:
- Change CSS variable selector from :root to body in _generate_css()
- Same specificity + later source order ensures our override wins
