/* ============================================================
   Advance Software — v8 CIRCUIT GRID
   The logo's circuit-node motif as the design system:
   dot-grid substrate, hairline traces with right-angle bends
   terminating in node circles, chip-package cards, one steel accent.
   Palette (from brand kit):
     deep navy bg   #0C1E2B
     darkest navy   #07121B
     steel accent   #68A0B0  (brand)  /  #80BACC (lightened, on dark)
     off-white text #F0F7FA
     muted steel    #96AFBC
   Rule: dark navy base + ONE steel-blue accent. Never a second accent.
   Type: Poppins — Bold/ExtraBold ALL-CAPS headlines; IBM Plex Mono labels.
