+    "body": "Every road, railway and tile work now rises as an economic construction site instead of a queue entry. A site gathers its materials over days from reachable regions, refusing any supplier quoting above the price it was budgeted at (a 1% tolerance); a day that buys nothing stalls the site, raising a red mark and letting the nation raise the budget to current prices or cancel it. The upfront budget covers the build cost plus the market value of its steel and high-tech, energy stays a grid draw, and any money left over stays with the finished work as a maintenance reserve.\n\nThat reserve now pays the work's own daily steel and high-tech wear before the treasury is billed, so a well funded work spares the state until it runs dry; the spent money is paid into the nation's regions. Building upgrades run through the same gather-build-maintain machinery, sharing the site's kind flag and target level. The legacy tile-work queue and the market building are gone.\n\nBundles the in-progress chart sizing for the central bank panel."
