 * Hero block.
 *
 * Values mirror the Tilda original (bebestschool.kz, record rec591697013 — a
 * CR30N slider with a Zero block in each slide): 1200 px grid, 680 px tall,
 * 62/55/52/48/34 px headings in ApercuPro, #f66746 headings, #1cb65a buttons,
 * yellow #ffd62c arrows and dots.
 *
 * The Zero blocks placed every element by hand at each width; here the text
 * and the picture sit in two columns that flow instead, and stack below 640 px.
