Create a beginner-friendly responsive file detail card using semantic article, heading, description list metadata, a labelled progress status, and real action buttons. Keep every custom selector under .cf-file-card and ensure every selector is represented in the supplied HTML so live CSS edits visibly update the preview. Use readable contrast, a non-color file-type cue, an explicit upload status, 44px touch targets, visible keyboard focus, responsive stacking from 320px, and reduced-motion handling. Do not use JavaScript, external assets, framework classes, or icon fonts. Return complete copy-ready HTML and dependency-free CSS, then explain why the metadata uses a description list and why status is announced beyond color.
