Supply Chain Command Center

Build a Supply Chain Command Center — an S&OP exception dashboard on 24 months of simulated data (5 product families × 4 regions × 480 data points). Include:

- Health score gauge (fill rate 50% + forecast accuracy 30% + inventory health 20%) with clickable score decomposition
- KPI cards with SVG sparklines and pill badges showing month-over-month deltas
- Portfolio health trend chart with colored reference zones (critical/watch/healthy) and event annotations (APAC disruption, crisis, holiday, recovery)
- Timeline play button with speed control and event badges to jump to key moments
- Demand Shock scenario slider (±30%) showing live fill rate and health score impact
- 4 tabs: Overview · Products (demand plan vs actual vs shipped) · Regions (APAC disruption callout) · Heatmap (120-cell fill rate grid, click to drill down)
- 8-step guided Story Mode with auto-narration, pause/resume, and progress bar
- 2025 Wrapped year-in-review modal with shareable stats
- 6 themes (3 light, 3 dark) with glassmorphism cards
- Summary bar showing worst/best/avg months with click-to-navigate
- Engineered story beats: Q2 2025 APAC supply disruption → Electronics crisis at 48.6% fill rate → Q4 2025 holiday divergence → Q1 2026 Apparel overstock → recovery

Data generated inline using DuckDB generate_series with deterministic sine-wave variation and engineered disruption events.
