/* LeadOcto - shared site chrome (top nav + footer) for the 2026
 * redesign. Ported from the design bundle's per-page topnav/footer
 * markup, unified into one stylesheet, and extended with the mobile
 * nav + language switcher the marketing prototype did not include.
 *
 * Every chrome class is `lo-` prefixed so it never collides with the
 * page-scoped class names ported into lo-home.css / lo-pricing.css /
 * etc. (those keep the design's original `.hero`, `.footer`, ... names
 * but only for in-page sections).
