the binary serves the face it names

pkg/api embedded 56KB of genuine Geist and served it at /fonts/Geist-Variable.woff2, and the landing page's @font-face asked for it by name — so mpc.hanzo.ai painted its only pre-auth surface in a typeface the estate does not use. The bytes are Zen now; checked at the name table, family 'Zen', with the OFL notice the licence requires intact.

The dashboard was worse than wrong, it was blank: its layout published --font-geist-sans off the geist package while tailwind.config.ts asked for --font-zen-sans, so font-sans resolved to nothing and every screen fell back to the browser default. The docs layout imported Zen under the name GeistSans, which compiles and lies.
