/* The partner site's own layout. Two layers:
 *  - the FRAME (header, footer, home hero, headings, buttons, cards) takes ivendnext.com's look: its font, ink, accent, pill
 *    buttons, round cards and night-blue footer, measured from the corporate site on 2026-10-08 and kept here as --site-*;
 *  - the BODY (text, links, tables, code, notes) keeps the kit's own tokens (assets/ivn-kit.css, copied from kit/design/), so
 *    the pages read like our product, in light and dark.
 * Logical properties only (right-to-left safe). No script; nothing is fetched from another host: the font and the logo are
 * copied into assets/ from site/assets-src/. Every text colour pair is at least 4.5:1 in light and dark. */
