/*
 * public/site/nav.css — the floating top bar created by public/site/nav.js.
 *
 * Hidden by default; nav.js adds `.is-visible` when the visitor scrolls up
 * below the hero. Colours match the page (#15151A ground, cream text).
 * The inner row uses the same max-width and side padding as the page's own
 * content column, so the logo lines up with the content beneath it.
