/**
 * Fallback ticker → GICS sector mapping for common US stocks.

 * Used when Alpha Vantage metadata is unavailable (rate-limited, network error,
 * or the ticker is not covered). Covers all S&P 500 mega-caps and a broad
 * selection of large/mid-cap names (~240 tickers).
 *
 * GICS sector names used throughout this map:
 *   "Information Technology"
 *   "Financials"
 *   "Health Care"
 *   "Consumer Discretionary"
 *   "Consumer Staples"
 *   "Energy"
 *   "Materials"
 *   "Industrials"
 *   "Utilities"
 *   "Real Estate"
 *   "Communication Services"
 *
 * If a ticker is not found here and Alpha Vantage also fails,
 * callers should default to "Unknown" and apply market-level shocks.
