If the cart total falls under multiple rules — which one applies?
The rule with the closest matching threshold applies. Example: two rules — "from $5000 — approved by travel manager
Svetlana" and "from $200,000 — approved by director Anna". Then a $500 cart needs no approval (below all thresholds);
$30,000 cart — Svetlana ($5,000–$200,000 range); $250,000 cart — Anna (above $200,000). This builds multi-level control:
small amounts approved by the travel manager, large ones by the director.
