/* ============================================================
   THE LOGICAL TECH — Design System v2 "Ledger"
   Concept: precision on both sides of the business — engineering
   rigor (logic, systems, code) and financial rigor (ledgers,
   term sheets, cap tables). Expressed through hairline rules,
   monospace data labels, and a single confident accent color,
   with a muted brass tone reserved only for capital-side marks.
   Signature: a quiet monospace status line in the hero — read
   like a system log or a ticker — instead of decoration.
