/**
 * Choice components + product-page sticky CTA.
 *
 * ADR-004: products have no prices, so quantity tiers and the price summary
 * were removed. Option groups/cards/chips remain for choice UIs such as the
 * general quote page (/teklif/). The sticky bar jumps to the product quote
 * form. Loaded on product pages and the quote page.
 *
 * Components: option-group · option-select · option-chip · option-card ·
 * option-reason (incompatible) · file-upload · sticky-mobile-bar
 *
 * All choices are native radios/checkboxes inside fieldset+legend.
 * Incompatible values use aria-disabled (stays focusable, reason is read).
