🏎️

Structured Schema

5 types: hobbyCategory, collectibleItem, collection, priceHistory, wishlist. Relations + GROQ for median valuation.

📈

Price Intelligence

priceHistory per item → GROQ query calculates median, detects outliers, 30-day trend.

🎯

Wishlist Alerts

Target price vs market price → trigger alert when price drops to your budget.

GROQ Example — Portfolio Valuation

*[_type == "collectibleItem" && status == "owned"]{
  title, purchasePrice, currentValue,
  "trend": *[_type=="priceHistory" && item._ref==^._id] | order(recordedAt desc)[0..9]{price, recordedAt}
} | { "totalPurchase": sum([].purchasePrice), "totalMarket": sum([].currentValue), "gain": sum([].currentValue) - sum([].purchasePrice) }

This query only works because content is structured — keyword search cannot calculate gain/loss.
