/**
 * LTC Shell — global site header and footer.
 *
 * Global chrome only: logo, primary navigation, programme dropdown,
 * mobile drawer, conversion CTA, and the footer lead-in/nav/baseline.
 * Depends on ltc-tokens.css / ltc-base.css / ltc-components.css for
 * colour, type and button primitives — this file adds only the
 * structural/positioning rules those primitives don't already cover.
 *
 * Progressive enhancement: the primary <nav> markup is used once and
 * reused for both the inline desktop nav and (under .js, on narrow
 * viewports) the mobile drawer — there is no duplicate nav in the DOM.
 * Without JavaScript the nav and programme sub-list stay in normal
 * document flow, fully visible and reachable.
