  Generate a native PowerPoint (.pptx) file with magazine-grade editorial
  styling — pitch decks, investor presentations (路演 PPT), board reviews,
  executive memos, conference talks, product launches. Output is a single
  .pptx file generated via pptxgenjs through the JavaScript executor runtime, openable
  in PowerPoint / Keynote / Google Slides. Uses five named editorial palettes
  (Monocle, Indigo Porcelain, Forest Ink, Kraft Paper, Dune) with strict
  typography rules (Georgia display + Calibri body) and 10 numbered layouts
  (L01 Cover, L02 Act Divider, L03 Big Numbers, ..., L10 Closing).
  Prefer this skill over the builtin presentation-generator whenever the
  user wants a polished editorial look, names one of the five palettes,
  asks for a "美观 PPT" / "投资人路演 PPT" / "pitch deck", or otherwise
  signals that visual quality matters beyond a generic deck.
  Use `html-deck-editorial` instead only when the user explicitly wants HTML
  output (more visual freedom but not Office-compatible).

  When the user wants a polished native .pptx deliverable (pitch deck, 路演 PPT,
  board review, executive memo) where visual quality matters and the file must
  open in PowerPoint / Keynote / Google Slides. Use `html-deck-editorial`
  instead when the user explicitly wants HTML output.

Editorial PPTX Deck

You will generate one `.pptx` file by writing a JavaScript program that uses **pptxgenjs** and runs it via the `execute_javascript_code` tool. Save the file to the workspace (use the output dir the tool returns), then report the path and a 1-line layout summary.

⚠️ Hard rules — NO exceptions

0. **MATCH THE USER'S LANGUAGE.** This is rule zero, the most violated rule. If the user prompt is in Chinese (中文), EVERY string in the deck — kickers, slide titles, body text, captions, kicker labels, folio prefixes, sample names, captions — must be in Chinese. **NEVER** copy English template phrases like `THE PROBLEM`, `FEATURE STORY`, `RESEARCH BRIEF`, `THE BOTTOM LINE`, `BUILT BY BUILDERS` into a Chinese deck. Translate them: e.g. `THE PROBLEM` → `问题所在`, `THE SOLUTION` → `解决方案`, `MARKET OPPORTUNITY` → `市场机会`, `THE TEAM` → `团队`, `USE OF FUNDS` → `资金用途`, `THE BOTTOM LINE` → `一句话总结`, `RESEARCH BRIEF` → `研究简报`, `CASE STUDY` → `案例研究`. Person names in a Chinese deck should be Chinese names (e.g. 张伟 · 陈琳), not transliterated English names. Folio reads `01 / 12` in either language (digits are universal). Same applies to other languages: match the prompt. 1. **One palette only.** Pick one of the 5 palettes below, use only its 4 hex values. Never invent new hex. 2. **Two fonts only.** Display = `Georgia` (serif, present on all OSes). Body = `Calibri` (sans, Office default). No custom fonts — `.pptx` recipients won't have them and the deck will fall back to Times. **For Chinese decks**: Georgia + Calibri both render Chinese via system fallback fonts (PingFang on macOS, Microsoft YaHei on Windows) — that's fine, do not switch to custom Chinese fonts. 2a. **🚫 NEVER apply `charSpacing` to CJK / non-Latin text.** The trick of "tracked-out caps" only works for Latin letters (`A B C D`). On Chinese, Japanese, Korean characters — which are already full-square glyphs — `charSpacing: 10` (0.10em) renders as `部　署　周　期` with huge gaps between every character. This looks broken on EVERY rendering platform. Rule: if the text contains ANY CJK character, set `charSpacing: 0` (or omit the property entirely). Only apply `charSpacing: 8-15` when the entire string is uppercase Latin (e.g. `RESEARCH BRIEF`, `PART 02`). For Chinese kickers, just use bold + small caps look via 11pt bold ink-tint text WITHOUT any character spacing. 3. **Forbidden visual elements** (PowerPoint defaults to these — you must actively avoid):

• drop shadow / glow / reflection / soft edge / bevel / 3-D rotation
• gradient backgrounds
• rounded rectangles (use `rectRadius: 0`)
• clipart, emoji as decoration, stock-photo placeholders
• Comic Sans, Times New Roman default, Arial Black
• smart-art with default styling
• rainbow chart palettes (chart uses ink + paper-tint only)

4. **Real content only.** No lorem ipsum, no `[Title here]` placeholders, no fabricated statistics. If a slot has no user data, drop the slot.

• **Team slides especially**: if the user did not provide team names,

titles, or bios, DO NOT invent them. Don't make up `陈明远 · 前阿里 云智能平台总监 · 清华大学计算机硕士` — that's fabrication and looks fake to anyone in the industry. Either ask the user for team info OR drop the team slide entirely and note "团队信息待补充".

• Same for fake financial metrics (MRR / ARR / growth rate), fake

customer names, fake competitive comparisons. If you don't have it, don't ship it. 5. **Slide count is driven by content.** 6–12 short, 15–25 long. No padding. 6. **Fill the slide.** The 13.33 × 7.5 inch canvas is large. Do NOT cram everything into the left third. Use `align: 'center'` on hero text, place the body block across columns 1–11 (x: 0.7 to 12.6), use the full vertical range top-to-bottom. A slide that looks 60%+ empty is broken. 7. **Sizing for Chinese text**: Chinese characters take MORE horizontal space per char than Latin. Rules of thumb:

• Hero title at fontSize 40-48: give the textbox at least `w: 12` inches

(the full content width). Title at `w: 6` will overflow / wrap badly.

• 1 Chinese character at 40pt ≈ 0.55 inch wide. Plan accordingly.
• For section titles (24-28pt) keep `w` ≥ 8 inches.
• For body text (14-16pt) `w: 11+` is safe for full sentences.

8. **No overlapping shapes.** When you place a dark section header / banner on a slide, leave at least 0.3 inch of vertical clearance before any text shape. Banners at `y: 1.2, h: 0.8` should not have a title
