   Palette:
     --color-primary: #2a2a2a  (charcoal — replaces navy)
     --color-accent:  #e8743a  (warm orange — replaces amber)
     --color-bg:      #ffffff  (white base)
     --color-cream:   #f5f1ea  (warm cream — neutral)
   Typography: Inter / Poppins via Google Fonts.
   Inter 400/500 for body, Poppins 700/800 for display headings.
   All transitions unified to 0.4s ease.
