Grace notices what the numbers miss. A child’s crooked laugh that costs nothing but changes the day; a nurse whose hands carry years of steady work and unpaid overtime; a rooftop garden where tomatoes ripen for no one’s balance sheet. In a back alley a mural, half-faded, reads: "Measure what matters." Someone painted it a year ago; weather and neglect have taken the edges, but the words remain like an insurgent math.
