Typography

Real font stacks pulled directly from each site's own global.css, rendered with the actual typefaces so the character comes through, not just the numbers. All three share Plus Jakarta Sans for body text and IBM Plex Mono for data/mono, but diverge sharply on headings: MarketInvoice stays in Plus Jakarta Sans bold, FundBiz uses Bitter (a serif chosen to differentiate it from sister BBL sites), PeptideClear uses Source Serif 4. None of the three defines a formal h1-h6 scale in CSS, sizes are applied per-instance via Tailwind utility classes, so the figures below are what's actually in use on real pages, not a declared token.
