   AMB GROWTH ACADEMY — stylesheet
   -----------------------------------------------------------------------------
   Design tokens
   Color   #0A0B0D near-black canvas · #16181D charcoal surface ·
           #F7F7F8 off-white section · #FFFFFF card ·
           #3D5CFF electric-blue accent (used sparingly: CTAs, numerals, links)
   Type    Display  — "Space Grotesk", tight tracking, used only for headings
           Body     — "Inter", generous line-height for long-form text
   Motif   A single hand-drawn "growth path" line (SVG) introduced once in the
           hero and echoed, quietly, as the numbering style in the Método and
           Academia sections — the throughline between "attention" and "client".
