Split the quiz out of one giant file into data.js, quiz.js, scoring.js, render.js, with a basic test harness for calculateResults(). Then fixed the actual scoring bug: careers used to win on being consistently “meh” across every question instead of nailing a couple of perfect matches. Added a bonus for 3/3 scores on 2+ questions, confidence labels (“Strong Match” / “Worth Exploring”), and tracking for which questions drove each career’s score.
