 *  SRPEPL — Industries Pages Global Stylesheet
 *  Link on every industry page AFTER srpepl-global.css:
 *
 *  <link rel="stylesheet" href="/assets/css/srpepl-global.css">
 *  <link rel="stylesheet" href="/assets/css/srpepl-industries.css">
 *
 *  Design intent: same brand language as solutions pages, but
 *  visually distinct — denser, more technical, credential-forward.
 *  Key differences from srpepl-solutions.css:
 *    · Amber/gold accent (--ind-gold) for live-project evidence
 *    · Taller hero with a 5-stat strip
 *    · Solution intervention cards on a process spine
 *    · Dense case-study cards with spec tables
 *    · Credentials wall (client tile grid)
 *    · Two-loop / two-column comparison blocks
 *  Page-specific overrides go in a <style> block on each page.
