   --color-bg-primary   (#0E1711 near-black forest green) : Main page/hero
                          background, header background, primary dark surface.
   --color-bg-secondary (#213024 deep green)               : Alternating
                          section backgrounds, cards, portfolio placeholder
                          tiles — sits one step lighter than primary.
   --color-cream         (#F2EAE0 warm off-white)           : Primary text
                          color on dark surfaces, button text on red CTAs.
   --color-accent-red    (#851B12)                          : Primary CTA
                          button backgrounds, important highlights.
   --color-accent-gold   (#BD8723)                          : Icons, borders,
                          hover states, active nav links, dividers.
   --color-espresso      (#211308 deep brown)                : Footer
                          background, deep shadows.
   No hardcoded hex values are used below this point — every color reference
