/* FitLife styles — v2 "Fresh Green" theme.
   Type: Space Grotesk for headlines and numbers, DM Sans for everything else.
   Colour: paper white/green with a deep-green + lime brand, amber/orange kept for streaks and "today".
   Layout is fluid (clamp()) AND has explicit desktop / tablet / mobile tiers — see the
   responsive section near the bottom for the three breakpoints: 1024px (tablet), 860px
   (tablet portrait / phablet) and 640px (phone). */
