## Cleo Directive

Use this as a candidate PPT Style design system. Cleo must judge fit first, then output an adapted or recreated style contract with candidateSlug=ppt-style-template-cartesian, visual rationale, tokens, layout tendencies, and anti-rules.

## Mood

- quiet
- considered
- elegant
- warm-minimal

## Layout Rules

- Cleo 必须按 mood、tone、occasion、best_for、formality、density、scheme 做风格匹配；这是一套闭合模板系统。
- 保留 Playfair Display / Inter、调色板、网格节奏、装饰语言和导航姿态；不要和其他模板混搭。
- 先用真实用户主题替换 demo 文案，再扩展逐页内容；不允许把模板说明、prompt 原文或“如何制作 PPT”的过程写进页面。
- 如果用户没有指定具体模板，Cleo 可以基于场景和情绪推荐 3 个候选，但最终 deck 只采用一个模板系统。

## Forbidden

- 不输出 PPTX；v1 只生成 HTML Deck。
- 不保留 [必填]、TODO、SLIDES_HERE 或模板注释残留。
- 不让模型改坏固定导航脚本、stage 尺寸或 overview 结构。
- 不要用于：Decks needing urgency, heat, or many accents.
- 不要把 模板画廊当作普通 Skill；它只属于 PPT Style 设计系统资源。
- 不要保留模板示例里的品牌、数字、人物、按钮文案或占位截图。

## Sable Boundary

This resource is not a special Skill. Sable may cite generation and QA skills, but must not select this PPT style as a skill.

## Prompt Lines

- Cleo evaluates candidate ppt-style-template-cartesian from the PPT Style library, then adapts or recreates the final style contract.
- Deck artifact remains HTML with metadata artifactType=ppt-deck.
- Elara uses Cleo's adapted style contract with Sable's PPT generation skills.
