The\nquiz scores all nine Belbin team roles, shows your top roles with strengths and\nallowable weaknesses, lets you download a PDF of your profile, and offers a\n**shared team board** so everyone who enters the same team code shows up on one\nboard with their top roles.\n\n## Access\n\nThe app is public by default, so anyone with the link can take the quiz. Only a\nperson who matches the team code influences that team's board — the quiz itself is\nfully client-side and no answers leave the browser unless someone adds themselves\nto a team board.\n\n## How it's built\n\n```\nmain.tsx Hono routes (the HTTP entry)\n / serves the quiz (frontend/quiz.html)\n /api/team (GET) reads a team board by ?code=\n /api/team (POST) adds/replaces a member, returns the updated board\n /dashboard leftover artifact uploader from the original template\nfrontend/\n quiz.html the entire quiz UI + client-side scoring and rendering\nbackend/\n team.ts team board storage in project-scoped SQLite\n```\n\n## Team board\n\nAfter finishing the quiz, a viewer enters a name and a team code. The app stores\n`{code, name, topRoles}` in the val's SQLite database. Anyone opening the link and\nusing the same code sees the same board — each member's top role(s), plus which of\nthe nine roles aren't naturally covered yet.\n\nThis replaced the original `window.storage` implementation, which only worked\ninside Claude Artifacts.
