/* ==========================================================================
   Smartech — style.css  ·  "Bold Vibrant Gradient" theme
   Energetic orange gradients, big rounded shapes, soft warm shadows.
   Brand colours are injected as CSS variables by generate.js
   (see <style id="theme-vars"> in index.html). Edit base colours in .env.
   JS-coupled mechanics (slideshow, projects carousel, loader, reveal,
   mobile nav, form) are preserved — only the look is rebuilt.
