A three-plan pricing section with a gliding Monthly/Yearly pill switch and a Save 20% badge; the featured plan sits on a dark card. Plan Card component props: name, popular, description, monthlyPrice, yearlyPrice, feature1-6, showFeature5, showFeature6, ctaLabel, ctaHref, dark. Both billing figures render in the markup so the price already swaps with no JavaScript (a real radiogroup, click or arrow keys); JS enhances the swap into a rolling-digit odometer transition. Section options: data-billing (monthly|yearly) default selected cycle.
