/* Professional Gutter Cleaning in Nashville — homeowner guide.
   Composition: a worksite field guide. A slim fixed rail, a deep-green
   opening field carrying the answer, then
   alternating full-bleed fields — sheet, tint, field, sheet, field —
   so every H2 owns a visible region without repeating a box.
   Mobile-first. System fonts. One small same-origin script. */
