   THEVERTECH — VISUAL ENHANCEMENT LAYER  (enhance.css)
   Loads AFTER style.css. Purely additive & reversible.
   Goal: take the existing dark/purple brand and make it read
   like a premium agency build — better type, atmospheric depth,
   tinted shadows, machined card surfaces, glass nav.
   Everything keys off the existing CSS variables so it adapts
   to both dark and light themes automatically.
