   Zikukim — Design System v2 (Premium SaaS layer)
   --------------------------------------------------------------------------
   This file is loaded AFTER style.css and elevates the whole product without
   touching any business logic or page markup. It is written as an additive
   layer: refined design tokens, premium card/button/table/form/modal/badge
   styling, scroll-reveal + stagger animations, animated counters/progress,
   micro-interactions, skeleton + empty states, and a mobile "table → cards"
   pattern.

   Architecture note: everything reads from CSS custom properties so a full
   Dark/Light toggle can be layered on later via [data-theme="dark"] with no
   markup changes.
