   GLASS.CSS  -  Liquid-Glass redesign   (loaded LAST on every page)

   1.  Colour tokens (light + dark, balanced mixed palette)
   2.  Page background: aurora + floating bubbles
   3.  Text: readable headings, gradient typing, letter wave
   4.  3D glass cards + water WAVE on hover
   5.  Navbar + theme switch
   6.  Buttons
   7.  Hero / profile card
   8.  Sections, feature cards, rings, technologies
   9.  Inner pages, forms, contact
  10.  Projects  (3 cards per row, 3D glass-water)
  11.  Project modal
  12.  Footer, toast, misc
  13.  Responsive + reduced motion
