/**
 * ifinsta Desktop — public chrome (canonical header, footer, buttons)
 *
 * The one header and footer every public page uses: marketing pages
 * (base_marketing.html) and the guest surfaces — Discover, the public booking
 * store, checkout, car hire, ticketing (base_guest.html). Page styling lives in
 * marketing.css (marketing) or guest.css (guest surfaces); this file only owns
 * the chrome around them.
 *
 * Same rules as marketing.css: no shadows, no literal colours, every class
 * ifinsta-mk- prefixed. The chrome follows the theme (light by OS default via
 * Auto, black in dark mode) through the semantic --ifinsta-mk-* tokens.
