/*
 * Berkshire Local Nature Partnership — site stylesheet.
 *
 * The palette and type are deliberately the same as the map story at
 * /explore/ (engine/src/styles/main.css), so moving between the two feels
 * like one site: a warm off-white paper, deep green ink, one accent green.
 *
 * Headings are set in the story's serif; running text is set in a system
 * sans for readability on long policy-ish pages.
