   Brand kit note: the account brand kit specifies Oswald (headings) and
   Inter (body), but no self-hosted woff2 files have been supplied via
   add_site_assets yet. Per the no-render-blocking-fonts rule we cannot
   link Google Fonts, so this stack uses system fonts tuned to read close
   to Oswald/Inter (bold condensed-ish headings, clean grotesque body).
   Swap --font-heading / --font-body below the day real font files land.
