   COLOR SCHEME
   ==============================================
   To change the site's color scheme, edit ONLY
   the variables below. Everything else adapts
   automatically.

   --color-primary       Main brand color (nav buttons, links, stats bar)
   --color-primary-light  Hover/lighter variant
   --color-primary-dark   Headings, hero backgrounds, page heroes
   --color-accent         CTA buttons, labels, highlights
   --color-accent-light   Accent hover / footer icons
   --color-accent-dark    Accent pressed state
   --color-text           Body text
   --color-text-light     Secondary/muted text
   --color-text-inverse   Text on dark backgrounds
   --color-bg             Page background
   --color-bg-alt         Alternating section background
   --color-bg-dark        Footer / dark sections
   --color-border         Card & input borders
   --color-success        Success indicators

   The *-rgb variants hold the R,G,B channels
   so they can be used with rgba() for opacity.
