/* =============================================================
   BODY TAB — SUMMARY HUB
   "At a glance" grid rendered inside #bodyTab by body-hub.js:
   Weight and Macros as full-width cards (sparkline / macro bars),
   Sleep and Cardio side by side (7-day bars). Reuses the pod
   language (design-system.css) — kicker/value/sub stacked the way
   .stat-tile does, sized up for a headline number per mini-tab.
   Depends on: tokens.css, design-system.css
