html-ppt-zhangzara-cartesian

This skill generates a single self-contained HTML presentation deck with a quiet, warm-neutral palette and classical Playfair serifs, designed for formal, low-urgency content like investment theses, research papers, and advisory materials. Use it when the presentation needs to convey restraint and considered judgment rather than visual impact or urgency.

# 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.
