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
- Clone
example.html into the user's workspace as the working file.
- Replace placeholder content with the user's real headlines, body copy,
numbers, names, dates, and section labels. Match existing dimensions when
swapping image placeholders.
- 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.
- 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.
- 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.
- Keep the navigation runtime as shipped. If the deck ships an
assets/deck-stage.js or inline keyboard handler, leave it intact.
