Synapse

A clinical teal seed (#006A6A) keeps long study sessions calm: tonal surfaces carry depth, Roboto stays readable, and filled buttons plus a navigation bar mark the next step. Flagged states stay on the error role. The quiz session stays quiet, with the timer secondary, and analytics uses linear progress. This avoids the default purple seed, shadow-stacked cards, decorative charts, and an answer key during a question.
