/* ═══════════════════════════════════════════════════════════
   GATED DOWNLOAD FORM  (.rdf-*)  — SHARED COMPONENT STYLES
   Markup: template-parts/promo-cards/download-form.php
   Behaviour: custom-assets/js/resource-download-form.js
   Handler: intone_handle_resource_download_form() in functions.php

   Extracted out of single-post.css (2026-07-31) because the same
   component is now embedded outside a single post: the Public Sector
   page's lead-magnet band renders it too, and single-post.css never
   loads on a page. Enqueued by intone_resource_form_assets() wherever
   the form actually appears, so there is one copy of these rules and
   no chance of the two surfaces drifting apart.

   Layout that is specific to the single-post SIDEBAR (stacking order,
   narrow-column max-width) deliberately stayed behind in
   single-post.css — it is not a property of the component.
