/* ============================================================
   WE ELEMENT LTD — Custom styles & design tokens
   ------------------------------------------------------------
   Tailwind (via CDN) handles most layout/spacing utilities.
   This file holds:
     1. Brand colour + type variables (CSS custom properties)
     2. Base element styles (fonts, smooth scroll, selection)
     3. Reusable component classes (buttons, eyebrows, cards)
     4. Scroll-reveal animation classes used by script.js
   Plain CSS so it ports cleanly into WordPress.
