/* ============================================================================
   GreenReach shared marketing brand — global CSS for the Community + Vendor pages
   ----------------------------------------------------------------------------
   SOURCE OF TRUTH: the brand is defined by the marketing site (purchase.html,
   greenreach-org.html, grow-and-sell.html) — a LIGHT theme with green accents
   and the Apple system font. This file makes every Community/Vendor page share
   that exact palette, type, header, and footer (operator request, 2026-06-04:
   "none of your new marketing pages share any of the color, fonts, themes").

   HOW PAGES USE IT: load this stylesheet + community-nav.js (which injects the
   canonical <header class="site-nav"> + <footer class="site-footer">). Pages
   should DROP their own inline :root token block — the tokens below (and the
   aliases for the older --gr-* / --green / --card names some pages were authored
   with) resolve every var() reference to a BRAND value, so a page rebrands to
   light+green automatically once its dark :root override is removed.
