/* homepage.css - homepage only (front-page.php + template-parts/home/*).
   Sections map 1:1 to template-parts/home/*.php: lineup, rnd, oem, cases, showcase, inquiry.
   Cut out of the design source's site.css (wangcheng.factory07.site/assets/css/site.css) with
   declarations and order unchanged; the site-wide parts (design tokens, shared components,
   header, footer, reveal) live in style.css.
   Promote a block into style.css once a SECOND page uses it - that is what keeps style.css from
   growing as pages are added. Already there, so do not redeclare them below: .inq,
   .steps / .step, .ctaRow, .hero-pic, .chips, .link-arrow. Still homepage-only, because no second
   page has needed them: .lineup / .card family, .statement, .rnd, .oem, .cases, .showcase.
   A selector's base declarations and its @media overrides must stay in the same file.
