Mixing layouts across templates\nbreaks the system; stay inside this one.\n\n## At a glance\n\n- **Scheme:** light\n- **Formality:** high\n- **Density:** low\n- **Slides in demo:** 10\n\n## Best for\n\nAnything 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.\n\n## Avoid for\n\nDecks that need visual heat, multiple accents, or a sense of urgency — the warm-neutral palette is intentionally low-energy.\n\n## Workflow\n\n1. **Clone `example.html`** into the user's workspace as the working file.\n2. **Replace placeholder content** with the user's real headlines, body copy,\n numbers, names, dates, and section labels. Match existing dimensions when\n swapping image placeholders.\n3. **Preserve the design system.** Never substitute fonts, recolor the palette,\n restructure the layout grid, or strip decorative elements (corner brackets,\n paper grain, geometric shapes, illustrated SVGs). They are part of the\n identity.\n4. **Adjust deck length by duplicating layouts.** If the user has more content\n than the demo holds, duplicate an existing slide of the most appropriate\n layout. If less, drop slides from the bottom. Update page-number labels.\n5. **Designing missing layouts:** if a slide needs a layout the template\n doesn't have, design it from scratch using the same fonts, palette,\n decorative vocabulary, spacing rhythm, and component grammar — never bail\n to a different template.\n6. **Keep the navigation runtime as shipped.** If the deck ships an\n `assets/deck-stage.js` or inline keyboard handler, leave it intact.\n\n## Output contract\n\nEmit between `` tags:\n\n```\n\n\n...\n\n```\n\n## Source & license\n\nVendored from upstream MIT-licensed\n[`zarazhangrui/beautiful-html-templates`](https://github.com/zarazhangrui/beautiful-html-templates/tree/main/templates/cartesian).\n\nThe full upstream MIT license text — including the original copyright notice — ships in this skill at\n[`LICENSE`](./LICENSE) and must be redistributed alongside any copy of `example.html`,\n`template.json`, or any vendored `assets/` runtime.
