   Roberto Delacruz — Portfolio
   Palette note: pulled directly from the "Sorry to Bother You" (dir. Boots
   Riley) one-sheet campaign — saturated violet-purple, hot magenta/pink,
   and warm crimson-red stacked together, with the marketing's signature
   gold-yellow reserved as a subtle accent and then used full-strength for
   the closing "outro" (Contact) section, echoing the yellow character
   posters. Headlines borrow the poster's stacked, offset-shadow lettering.
