   Cohort Imagem & Vídeo · sales page (v3)
   Loads AFTER ds.css (Academia LP base). Aesthetic of the house and

   Inter Tight + Instrument Serif italic + JetBrains Mono (data only).
   The page's voice is motion: a hero "player" that plays the clone
   workflow like a video composition, a program monitor that follows
   the classes, an edit timeline. Quiet surfaces, moving content.
