/* =========================================================================
   The Planters' Guild — Generic guide-article styles (shared)
   Used by guide-article.njk for editorial pillars whose articles share the
   two-column guide layout (Window Box now; Substrate Library + Plant Library
   profiles next). Self-contained superset: the guide chrome (hero / layout /
   sidebar / prose / related) plus the in-body components those articles use
   (callouts, comparison table, recipe box, pillar-CTA, blockquote). Field
   Manual keeps its own field-manual-article.css (dossier + figures). Loads
   after tokens.css + base.css; site chrome lives in base.css. Tokens only:
   legacy --forest → --forest-pine, fonts → --font-serif/--font-sans.
