/* ============================================================
   LEGO Indices - design system
   Light, editorial-financial. References: Robinhood (restraint,
   whitespace, oversized tabular figures), S&P Dow Jones Indices /
   MSCI (factsheet gravitas, "as of" stamps, structured methodology).

   Intentionally NOT the generic AI/Tailwind look: no purple
   gradients, no glassmorphism, no heavy drop-shadow card grids,
   no emoji. Hairline rules, generous space, one restrained accent.

   Typography: editorial serif wordmark/display + system sans for UI
   and data. A self-hosted display face can be dropped in later via
   @font-face (font-src 'self' already permits it) without touching
   the markup.
