/* =========================================================
   STATS BAND
   -----------------------------------------------------------
   Design direction: "flight path" stats.
   - .stats-eyebrow gives the section a name, same pattern used
     elsewhere on the site (Case Studies, Process) for rhythm.
   - First stat (.stat-item--lead) is visually senior: bigger
     number, indigo accent, sets up "here's the headline result,
     here's the proof underneath."
   - .stat-rule is a 2px line that fills left-to-right when the
     item scrolls into view — ties to the brand's "performance /
     momentum" story instead of sitting static.
   - Label is placed ABOVE the number, styled as a small tag with
     a leading dash — this single structural inversion is what
     separates it from the generic centered number-over-caption
     template.
