   TICO PLUNGE · COMPONENT LIBRARY
   Cross-page, reusable UI. Page-specific components (product cards,
   calculator, etc.) live in their own page stylesheet.

   Interaction polish follows Emil Kowalski's design-engineering
   principles: strong custom easing, scale-on-press feedback,
   hover gated behind real pointers, origin-aware popovers.
