   Design tokens: near-black indigo surface, violet as the "AI/tech" voice,
   warm ember as the "human/teaching" counterpoint. Signature motif: a
   miniature prompt-strip — a chat input with a blinking cursor cycling
   through real teacher prompts — standing in for "IA como conversa de
   trabalho", not as a robot/brain cliché.
