Use Geist as the default sans font family name

Google Fonts, Bunny Fonts and Fontsource all publish the font as "Geist". "Geist Sans" is only on Fontsource, so the default token fell back to system fonts with the other providers. "Geist Sans" stays as a fallback for existing Fontsource setups. Matches shadcn/ui, which loads "Geist".

-### Tailwind utilities with the CDN
-
-The CDN stylesheets only include the utilities Basecoat uses, so classes like `bg-primary` or `text-muted-foreground` are not available. If you add the [Tailwind Play CDN](https://tailwindcss.com/docs/installation/play-cdn) for utilities, map Basecoat's theme tokens to Tailwind colors and restore the border color after Tailwind's preflight. Load this after the Basecoat stylesheet.
