/* ── Theme: cool slate, dark ──────────────────────────────────────────────
   A neutral dark theme: cool off-white text on charcoal, with a muted
   steel-blue accent. Clean system sans-serif for UI text; a monospace stack is
   kept only for the numeric readouts. Same variable contract as the shared
   tool-base.css, so the chrome recolours from these roles.
