/* =========================================================
   Algorex — design system
   Design system: light-dominant, single cyan accent (#25a9e0),
   navy surfaces for hero / CTA / footer. Mobile-first.
   Fonts: Space Grotesk (display) + DM Sans (body)

   COLOR TOKENS (single source of truth — all values verified
   via rendered computed styles):
     Core (7):
       --color-bg-primary    #ffffff   body / page background
       --color-bg-secondary  #f0f7fa   stat section, cards' soft panels
       --color-text-primary  #404041   body copy (blueprint body gray)
       --color-text-secondary #6b7280  muted / captions (blueprint gray)
       --color-accent        #25a9e0   brand cyan (CTA borders, dark-surface text/UI)
       --color-accent-hover  #1a90c5   blueprint hover cyan (used on dark surfaces)
       --color-border        #e2e8f0   hairline borders / dividers
     Derived for WCAG AA (lightness only, hue preserved):
       --color-accent-strong #1378a8   accent as text/fill on light (4.9:1)
       --color-accent-strong-hover #0f6d99
     Navy surfaces (from blueprint hero/footer):
       --color-bg-inverse    #0a1633   hero, CTA, footer
       --color-bg-inverse-2  #1a2238   deeper navy (blueprint heading navy)
       --color-text-inverse  #ffffff
       --color-text-inverse-muted #aab3c8  muted white on navy (8.5:1)
       --color-border-inverse #4f5a74  navy hairlines
     Status (blueprint callout-tip / error):
       --color-success #38a169 / bg #e6f9ee / text #22543d
       --color-error   #ff5c5c / bg #fdecec / text #c53030 (AA-derived)
   No component defines its own color.
