Infografia A4 isométrica de estructura editorial técnica

Educational infographic poster titled "A4 Infographic Layout" in portrait A4 layout, designed as an expert-reference educational infographic about technology/engineering document structure; text labels must be sharp, crisp, and fully readable in clean sans-serif typography. Create 4 numbered components arranged in a clear top-to-bottom sequence with bold headings, one-line captions, and precise isometric 3D visual elements.

1. heading: "Canvas Setup"; caption: "A4 page frame defines margins, columns, and safe text zones."; visual: isometric 3D A4 sheet standing upright with visible outer border, inner margin guides, a measurement ruler along one edge, and highlighted safe-area blocks in yellow over navy grid.
2. heading: "Header Block"; caption: "Title, subtitle, and key metrics sit in a strong top section."; visual: cutaway-style top band of the page showing stacked title bars, small metric cards, alignment guides, and icon placeholders, all rendered as layered isometric panels.
3. heading: "Content Modules"; caption: "Numbered sections organize diagrams, captions, and comparison data."; visual: middle page area divided into 3 modular content cards with miniature charts, icon-diagrams, caption strips, and numbered circular badges, shown as raised isometric tiles.
4. heading: "Flow and Footer"; caption: "Arrows guide reading order while footer holds legend and source area."; visual: bottom section with directional arrows linking modules, dotted connector lines, a compact legend box, footer information strip, and page-end alignment markers.

Show connecting flow with bold arrows moving from 1 to 4, dotted guide lines between sections, and large sequence numbers inside yellow circular markers. Emphasize a simple but technical composition suitable for expert reference. Visual style: isometric 3D editorial infographic, high-contrast yellow and navy palette with white accents, precise geometry, strong separation of panels, clean shadows, polished engineering-layout aesthetic, confident and analytical mood, magazine-grade editorial illustration, vector-clean lines, no photographic textures.

All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Render labels and headings in clean English typography (sans-serif). No real-brand logos, no copyrighted characters, no people that could be identified, no graphic medical content. If the topic touches a regulated domain (medicine, finance, law), keep the explanation conceptual and add no specific dosages, prices or legal advice.
