/* ============================================================
   Sathyamangalam Atlas — shared design system
   Used by every page under site/. Keep in sync intentionally —
   this file is the single source of truth for CSS across pages.

   Design system: restyled 2026-08-14 to match the palette/type/
   layout patterns of a reference land-trust site (warm light-first
   theme, terracotta/olive/pine palette, Poppins display + IBM Plex
   Sans body, dashed section dividers, card grids). See
   docs/atlas-design-restyle-2026-08-14.md for the full rationale.
   Headings use Poppins (Google Fonts) in place of the reference's
   paid Typekit serif, per an explicit licensing decision — see that
   doc. Theming mechanism (CSS custom properties + data-theme attr +
   prefers-color-scheme) is unchanged; only the values changed, and
   light is now the primary/default theme rather than dark.
