/* Nebraska OSP Basemap Builder
 *
 * The page is dressed as the thing it produces: a plotted drawing sheet.
 * Sheet border with corner ticks, faint drafting grid, drafting-style callout
 * headers, and a title block along the bottom that mirrors the real one the
 * builder writes into every layout - it fills in live from the form.
 * Palette and typefaces are inherited from blakeagjones.com so this reads as
 * part of that site rather than a bolted-on tool.
