/* ==========================================================================
   MyHandicapCalc — visual styling
   Mobile-first: base rules target small phone widths, enhanced at 700px+.

   Single accent, one hue family throughout: a vivid, yellow-leaning grass
   green (hue ~100°) chosen to read as sunlit turf rather than a generic
   "brand green" — deliberately warmer/brighter than a corporate forest
   green, and distinct from the cooler kelly/emerald greens common in golf
   branding. Only two steps of it exist (a working tone and its hover/
   emphasis shade); nothing else on the page introduces a second colour.
   Result numbers get no colour of their own — they're set apart by scale,
   weight and a rule in the same green, not a swap to a new hue.
