/* Logic Bunting P43 — EEI grid background consistency pass.
   Visual-only base layer for PCI/SPI/PEI/PPI/CCI/UI.
   Source of truth: Production EEI .grid-fade treatment.
   The grid sits inside each existing .ambient layer: above its base gradient,
   below its existing ::before/::after orb/glow effects, with no layout impact. */
