Hi — new feature pages and UI additions are currently on hold while we focus on code quality (see discussion #2651). This is a large feature PR (23 files, 1884+/1009-) — please hold it until the quality sprint wraps up. PRs for tests, refactoring, bug fixes, and docs are welcome in the meantime.

New feature/UI PRs are on hold during the code-quality sprint — see discussion #2651. We'll revisit after the sprint; tests, refactors, and bug-fix PRs are the priority right now.

This PR bundles three unrelated feature systems into one 22-file change: the weekly productivity dashboard, a full achievements system (src/components/achievements/* + achievements-config.ts), and a goals rewrite (src/components/goals/* + GoalTracker + goals API routes). That's impossible to review or land safely as a unit — a problem in any one blocks all three, and it overlaps your own #2717 (the focused weekly-summary) plus the other goals PRs in flight.

Please split it: keep #2717 as the weekly-summary PR, and open separate PRs for (a) the achievements system and (b) the goals redesign, each on its own so they can be reviewed and their UI checked independently. Closing this one in favor of that split — the individual pieces are welcome.
