/*
  DESIGN CONTRACT — Silex Infrastructure Hub
  Intent: an operational read-only console for Cronos builders, not a marketing dashboard.
  Density: compact registers and explicit measurement labels; unknown values remain visibly unknown.
  Surfaces: flat navy layers, one-pixel borders, cyan selection, no decorative gradients or glow.
  Responsive rule: data grids collapse to legible rows/cards without horizontal page overflow.
