A handful of small, self-contained UI experiments with live playgrounds you can tweak.

• Guided tour overlay — DIY Tour Demo: highlight any element, mask the page, and walk users through steps.
• CTA with promo tag — Button Discount: a gradient button topped with a floating “discount” label.
• Playful rainbow CTA — Button Mastery 12: animated hover effects, gradient icon tile, and confetti pieces.
