/* ===================================
   SayShan - Grid/utility compat
   Several pages (service pages, contact) are written with Bootstrap-style class names
   (row / col-* / g-* / spacing / flex helpers) but Bootstrap is not loaded. This is the
   small subset they use, with logical properties so RTL mirrors. Gutter = 1.5rem (g-4).
