# Vellum > Deep navy canvas with warm-yellow italic Cormorant serifs and a single dusty teal accent. A quiet, scholarly aesthetic. A single self-contained HTML deck — typography, palette, decorative system, and slide vocabulary are all tuned together. Mixing layouts across templates breaks the system; stay inside this one. ## At a glance - **Scheme:** dark - **Formality:** high - **Density:** low - **Slides in demo:** 9 ## Best for Anything that should feel scholarly, literary, and quietly intelligent: research synthesis, white papers, academic and policy briefs, advisory deliverables, longform editorial pieces, founder reflections. Equally strong for any deck — including tech, business, or creator work — that wants a calm, considered atmosphere instead of energetic visuals. ## Avoid for Contexts that need visual heat or pop — the navy + warm-yellow italic-Cormorant aesthetic is intentionally low-tempo. ## Workflow 1. **Clone `example.html`** into the user's workspace as the working file. 2. **Replace placeholder content** with the user's real headlines, body copy, numbers, names, dates, and section labels. Match existing dimensions when swapping image placeholders. 3. **Preserve the design system.** Never substitute fonts, recolor the palette, restructure the layout grid, or strip decorative elements (corner brackets, paper grain, geometric shapes, illustrated SVGs). They are part of the identity. 4. **Adjust deck length by duplicating layouts.** If the user has more content than the demo holds, duplicate an existing slide of the most appropriate layout. If less, drop slides from the bottom. Update page-number labels. 5. **Designing missing layouts:** if a slide needs a layout the template doesn't have, design it from scratch using the same fonts, palette, decorative vocabulary, spacing rhythm, and component grammar — never bail to a different template. 6. **Keep the navigation runtime as shipped.** If the deck ships an `assets/deck-stage.js` or inline keyboard handler, leave it intact. ## Output contract Emit between `<artifact>` tags: ``` <artifact identifier="zhangzara-vellum" type="text/html" title="Deck Title"> <!doctype html> <html>...</html> </artifact> ``` ## Source & license Vendored from upstream MIT-licensed [`zarazhangrui/beautiful-html-templates`](https://github.com/zarazhangrui/beautiful-html-templates/tree/main/templates/vellum).
