   3. CIRCUIT BOARD SVG OVERLAY PATTERN

   Pattern: PCB-style traces in #0D2B0D (dark PCB green) on

   Includes a fine substrate grid, 90°-routed traces, via
   pads at junctions, and SMD component footprints.
   The colour #0D2B0D is inherently subtle on pure black —
   just perceptible as texture, never distracting.
