   LEAD Futures Foundation — Spacing, Radii, Shadows, Layout
   ------------------------------------------------------------
   Generous, calm spacing. Soft (not pill-round) corners that
   echo the organic curves of the logo. Shadows are low and
   warm — never harsh; the brand feels grounded, not floating.
