   Stockdale Christian School PSP — Design Tokens
   Palette drawn from the school's own navy + gold shield, softened for a
   calmer, more contemporary read. Signature concept: "soft light" — gentle
   glowing color washes, echoing "the Father of lights" (James 1:17).
   Typeface: Pretendard throughout, so English and Korean share one voice.
