Previous implementation created all ~589 shapes (year + months + weeks + days) at once, causing visual chaos on load and broken zoom. New approach dynamically creates/destroys shapes per level: year shows 12 months, month shows 6 weeks, week shows 7 days, day shows time slots. Wheel prime pattern (2 ticks) prevents accidental zooms. Double-click resets to year view. Co-Authored-By: Claude <noreply@anthropic.com>
