/* ==========================================================================
   TrueDo — premium marketing site
   Flat, editorial design system (Pop-Site reference): off-white canvas, white
   cards with 1px hairlines, big black grotesque headlines, ONE blue accent,
   pill buttons, generous whitespace. NO gradients, NO glassmorphism, NO blobs,
   NO glows. Light is the default; dark is an equally-flat near-black variant.
   Class + variable names are unchanged so every page keeps working.
