/* AEKE .sg — the toggle-box card rows (the K1's machine and accessory rows).
 *
 * MEASURED ON aeke.com's K1 page at 1440, reading the rules the page itself applies:
 *
 *   .toggle-boxes--inner    grid, `padding: 0 50px`, `gap: 20px`, `align-items: end`,
 *                           `max-width: 1540px`, 4 columns of 316.2px
 *   .toggle-box             316x392 — `overflow: hidden`, `position: relative`, radius 4px,
 *                           `margin-bottom: 10px`
 *     image                 `padding-bottom` = the box's `--ratio-percent` (105.15% / 100%)
 *     button                60px, `padding: 10px 30px`, ground = the panel's ground,
 *                           label 17px/500, plus glyph 14x14 at `right: 25px`
 *     panel                 absolutely positioned at the bottom, radius `16px 16px 0 0`,
 *                           15px copy, 30px padding
 *   .section-header         `padding: 0 0 30px`, centred; title 34px/600, line-height 42px
 *
 * ## The one substitution
 *
 * Upstream opens the panel with `height: 97%`, and on the live page that resolves to **0px** —
 * the panel never appears, so all sixteen boxes carry copy nobody can read. The percentage asks
 * for a share of a containing block whose height comes from its own content, and upstream's inner
 * is `calc(100% - 60px)`, which has the same problem. Same box, expressed as `inset: 3% 0 0`,
 * which does resolve, and animated on `transform` because a height that was never definite is
 * not a height that can be transitioned. See the note in `sections/toggle_boxes.html`.
 */

/* The 70px of section spacing is a margin on `.toggle-boxes`, one level down, so the wrapper has
   to contain it — otherwise it collapses out and the section reports 825px where the live page
   reports 965. Same trap as the collapsed margins on the home page's rich-text blocks. */
