/* Blazor .NET 9 injects whitespace text nodes and a <resourcepreloader> element
   into <body> as side-effects of its head-outlet resource preloading. These
   whitespace nodes form an anonymous inline block as tall as the body's
   line-height (Bootstrap reboot sets html at 16px, body at line-height 1.5,
   giving 16px × 1.5 = 24px). This pushes all page content down and creates a
   spurious vertical scrollbar on every page even when content fits the viewport.

   Fix: set line-height: 0 on body to collapse those whitespace anonymous blocks
   to zero height. Then restore line-height: 1.5 on every direct child of body,
   which covers GoalFrame's own .page wrapper as well as any other elements
   (loading overlays, error overlays, third-party injections) that land directly
   in <body>. The 1.5 value is Bootstrap 5's body default and is safe for all
   descendants, since it cascades through the entire page tree from those roots. */
