/*
 * White paper download block (book cover + inline lead form), shared by the pages that offer
 * the ORMIT™-OpenJava white paper: download-the-oracle-forms-modernization-whitepaper and
 * products/OracleForms-to-Angular (EN + FR).
 * Same design as the closing section of products/oracle-forms-to-ai-agents (section 13 of
 * oracle-forms-to-ai-agents.css), with page-independent class names: every rule starts with
 * .wpd (class on the section), so nothing here can reach another block or page.
 * Motion: assets/pages/wp-download.js adds html.wpd-anim when motion is allowed; without it
 * (no JS, no IntersectionObserver, reduced motion) the book shows its final state.
