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. ## Output contract Emit between `<artifact>` tags: ``` <artifact identifier="zhangzara-cartesian" 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/cartesian).
