When switching between the 'Pro' and 'Max' plans, the active tab pill slides with a springy animation. The entire screen's accent color morphs seamlessly from gold (Max) to cyan (Pro), affecting the tab outline, checkmarks, card borders, and the main CTA button. Simultaneously, the single pricing card for Max transitions into a dual-card layout (Monthly and Yearly) for Pro, sliding horizontally from the right, while the feature checklist fades and staggers to reflect the new plan's offerings.
