/* haonchain.com — desktop responsive corrections
   Layered ON TOP of styles.css + polish.css.
   Goals:
   - Tablet (721-1023px): pillars 2-col, compare 2-col tightened, hero metrics 2x2
   - Wide (>=1280px): comfortable max-width, breathing room
   - Tighten section padding (96px -> 64px tablet, 48px phone overlap with polish.css)
   - Fix mobile blank-space gap
