/* ============================================================================
   FUND DETAIL — Redesign against the Funds Benchmark Design System (Phase B)

   Loaded AFTER fundbenchmark-design-system.css. Overrides the legacy
   .fd-* page-specific rules so the fund-detail page reads as an expression
   of the design system rather than its own custom aesthetic.

   Non-destructive: we leave the PHP markup intact and ride the existing
   DOM IDs/classes. Layout and visual tokens are re-pointed at design-system
   tokens (--surface, --text, --accent, --r-card, --shadow-card, etc.).

   Change log (2026-04-24):
     - Scrap the vertical carousel — render all 4 headline stats in a grid
     - Adopt the design-system chip pattern for every stat
     - Retype fund name + labels (Montserrat display / DM Sans body)
     - Unify card borders, radii, shadows
     - Button/pill/icon primitives pull from .fb-btn, .fb-pill
