 * Oasis 2030: One million trees by 2030
 * Editorial layout on the brand system (forest green, DM Serif Display,
 * Poppins). No monospace; numbers use Poppins tabular figures. Rhythm comes
 * from full-bleed colour bands (green / tint / white) and a two-column split
 * for prose sections. Built on design-tokens.css; self-contained.
