   FIRST STATE ACADEMICS · Design Tokens · "Diamond State" system
   1-on-1 tutoring in math + AP Social Studies.  Delaware, the First State.

   Brand register: modern, high-contrast, premium. Near-black ink, a single
   confident colonial blue (PMS 2945 C ≈ #00549F), warm amber for the social-
   studies track, crisp off-white paper. Clean grotesk type. No serifs, no
   navy-and-gold parochial feel.
