/**
 * the supplier-style cascading variant picker — Hausprint theme.
 *
 * Measured values from the live site:
 *   - Theme sets `html { font-size: 62.5% }` so 1rem === 10px. We use px
 *     directly to match the default product page's typography (label 15px,
 *     input 14px) instead of fighting the rem base.
 *   - Default product page: container 1140px, summary column 547px wide,
 *     variation_label 15px / 600, variation_select 14px.
 *   - the supplier: mainForm 435px wide, custom_select 14px, subTotal 14px/700,
 *     header_label 13px/700, accent rgb(142, 198, 71).
 *
 * Hausprint accent (#4C9F9C) substitutes the supplier's green throughout.
