/* =========================================================================
   APENTOMOTIS — Landing page styles
   -------------------------------------------------------------------------
   Brand palette (sampled from the official logo):
     • Golden yellow  #FFC93C  → primary action / accent / highlight surfaces
     • Petrol teal    #155263  → dark surfaces + ink (text) on light
   Rule of thumb: yellow is a FILL, never small text on white (contrast).
   Text uses petrol; light text sits on petrol. That keeps the brand bold
   AND accessible.
   Organized top-down: tokens · base · buttons · header · hero · stats ·
   problem · features · how · pricing · faq · demo · footer · utilities ·
   responsive · reduced-motion.
