/* ---------- Chakra Petch weight hierarchy ----------
   Now that Chakra Petch has real 500/600/700 (not just Bold), give headings a proper
   ladder instead of everything shouting at 800: big impact numbers stay heaviest,
   headings drop to semibold, small labels to medium. Placed last so it wins by source
   order. Keeps the sport/techy feel but reads far cleaner. */
