/*
 * DwellAtlas marketing site — v6 "Field Guide" design system.
 * Rebuilt 2026-05-30. Cartographic, editorial, premium.
 * Identity comes from the brand mark itself: a compass + house in teal.
 * Palette: Obsidian ink, Atlas teal, Compass mint, Compass gold, warm Ivory.
 * Type: Inter for everything readable; IBM Plex Mono for coordinates, plate
 *       numbers, and figures (the instrument layer). No display serifs (rule #16).
 * Signature texture: faint topographic contour rings + corner survey ticks.
 * Light theme default with intrinsically dark hero / bands / footer.
 * Dark theme via [data-theme="dark"], toggled bottom-right, saved to localStorage.
