Cartesian

Quiet warm-neutral palette with classical Playfair serifs; tasteful and unhurried.

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: light
• Formality: high
• Density: low
• Slides in demo: 10

Best for

Anything that should feel quiet, considered, and grown-up: investment theses, white papers, advisory work, longform research, gallery / cultural decks. Also a strong choice for editorial features, founder reflections, or any deck where restraint is the message — including across tech and finance.

Avoid for

Decks that need visual heat, multiple accents, or a sense of urgency — the warm-neutral palette is intentionally low-energy.

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.
