# HTML PPT · 暗底知识图谱

A focused entry point into the [`html-ppt`](../html-ppt/SKILL.md) master skill that lands the user directly on the **`graphify-dark-graph`** full-deck template.

## When this card is picked

The Examples gallery wires "Use this prompt" to the example_prompt above. When you accept that prompt, this card is the right pick if the user wants exactly the visual identity of `graphify-dark-graph` (see the upstream [full-decks catalog](../html-ppt/references/full-decks.md) for screenshots and rationale).
