/* ==========================================================
   Mobile polish layer (additive — desktop unchanged)
   Adds:
     · iOS-zoom prevention on text inputs (>= 16px)
     · WCAG 2.5.5 touch targets (>= 44 x 44)
     · WCAG 2.5.8 spacing between adjacent tappables
     · Long-word overflow safety in dense text views
     · Tighter gutters / smaller hero on very narrow screens
     · Cleaner step-down for multi-column metric rows
     · Scroll-snap for the horizontal tab nav
   No design changes; no token edits; no JS changes.
