Subject: [PATCH] Load Inter via Fontsource and set mono stack
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Self-host the Inter variable font through @fontsource-variable/inter
rather than a CDN, so the v2 type scale renders in Inter with no
third-party request. Import it from the theme and point --font-sans
at the "Inter Variable" family the package registers.

Add --font-mono as a Radix-style system stack: the design specifies
Menlo, an Apple system font that cannot be self-hosted, so it falls
back per OS (Consolas, Liberation Mono, Monaco, monospace).
