/* ==========================================================================
   TRADEON — Platform marketing design system
   ---------------------------------------------------------------------------
   Identity: the company that BUILDS the tools. Precise, engineering-grade,
   quietly confident. White-dominant with deep ink (#0e1524) used sparingly,
   platform blue (#2f6fed) as the single accent, cool grays, generous space.
   Signature device: the TRIPLE TRADEON RULE (two ink hairlines + one blue
   stroke) — the same three lines as the mark. Strong grotesque display
   (heavy system sans, tight tracking) + mono microtype for spec labels.
   No external fonts/CDNs (CSP-safe). Mobile-first, accessible.
   Single source of truth for every tradeon-site page.
