/* Shared by rankings.html (hub) and the individual stock-ranking content
   pages (top-gainers.html, top-losers.html, most-active-stocks.html,
   largest-companies.html, low-pe-stocks.html, dividend-yield-stocks.html,
   growth-stocks.html). All read data/homepage_snapshot.json -- see
   js/rankings.js -- so coverage matches screener.html/index.html's
   dashboard. Reuses the site's white-card / var(--color-border)-border /
   8px-radius table language from css/screener.css rather than introducing
   new visual language, but kept as its own file since these pages are a
   distinct feature (content pages, not a filter tool). */
