/*
 * Shared site chrome — the nav, phone menu, footer and store badges used on
 * every public page. Pages keep their own inline CSS for their content; this
 * file owns only the .sn-* (nav) and .sf-* (footer) blocks, so the two never
 * fight over a selector. The markup it styles is copied into each page; when
 * you change it, change it everywhere (grep for class="sn").
 *
 * Fonts: every page already loads Geist from Google Fonts.
