Subject: Open Design's feature business case for the plugin marketplace: the user pain, options, tradeoffs, and the measure of success. Audience: PM, eng, design, leadership. First ask only for missing essentials: audience, decision target, source-of-truth materials, deadline, and must-keep numbers. Then produce the slide plan, written slides, visual direction, speaker-ready structure, and a critic pass against this rubric: can cross-functional reviewers agree on the next irreversible step."

HTML PPT · 暗底知识图谱

A focused entry point into the html-ppt 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 for screenshots and rationale).

How to author the deck

1. Read the master skill first. All authoring rules live in skills/html-ppt/SKILL.md — content/audience checklist, token rules, layout reuse, presenter mode, the keyboard runtime, and the "never put presenter-only text on the slide" rule.
2. Start from the matching template folder: skills/html-ppt/templates/full-decks/graphify-dark-graph/ — copy index.html and style.css into the project, keep the .tpl-graphify-dark-graph body class.
3. Bring the shared runtime with the template. The upstream index.html links the shared CSS/JS via ../../../assets/... because it sits three folders deep inside skills/html-ppt/templates/full-decks/. Once you copy index.html into the project, those parent-relative URLs no longer resolve and base.css, animations.css, and runtime.js will 404 — meaning the deck never activates and slide navigation is dead. Pick one of these two recipes per project:
   • Recipe A — copy + rewrite (preferred): copy skills/html-ppt/assets/fonts.css, skills/html-ppt/assets/base.css, skills/html-ppt/assets/animations/animations.css, and skills/html-ppt/assets/runtime.js into a project-local assets/ (with assets/animations/animations.css), then rewrite the four <link>/<script> tags in index.html from ../../../assets/... to the matching project-local paths (assets/fonts.css, assets/base.css, assets/animations/animations.css, assets/runtime.js).
   • Recipe B — inline: read the same four files and replace each <link rel="stylesheet" href="../../../assets/..."> with a <style>...</style> containing the file's contents, and the <script src="../../../assets/runtime.js"> with a <script>...</script> containing runtime.js. Yields a single self-contained index.html. Either way, do not ship the upstream ../../../assets/... URLs verbatim into a project artifact — they only work in-tree.
4. Pick a theme. Default tokens look fine; if the user wants a different feel, swap in any of the 36 themes from skills/html-ppt/assets/themes/*.css via <link id="theme-link"> and let T cycle.
5. Replace demo content, not classes. The .tpl-graphify-dark-graph scoped CSS only recognises the structural classes shipped in the template — keep them.
6. Speaker notes go inside <aside class="notes"> or <div class="notes"> — never as visible text on the slide.
