/*
 * Pot choice under a plant (knowledge-views.php, frontend/plant-container.js).
 * Built in the bouquet builder's language: native radios styled as choice
 * cards, an apricot selected state with an ink rim, and a paper order bar
 * with a 1px ink rim and 16px corners that pairs the plant with the chosen
 * pot, holds the running total and the one action. Flat surfaces, no
 * shadows; icons come from the theme set (zf_brand_icon).
 *
 * Motion follows docs/design/design.json: ease-out under 300ms, transform
 * and opacity only. The cards sprout into place once when the list arrives,
 * waiting is the garden sprout, and the total bumps once when it changes.
 * Reduced motion keeps opacity fades only.
