+#!/usr/bin/env bash
+# Mix a BGM track into an MP4 video.
+#
+# Usage:
+#   bash add-music.sh <input.mp4> [--mood=<name>] [--music=<path>] [--out=<path>]
+#
+# Mood library (in ../assets/, matching bgm-<mood>.mp3):
+#   tech              — Apple Silicon / product keynote vibe, minimal synth+piano (default)
+#   ad                — upbeat modern, clear build + drop, social-media ad energy
+#   educational       — warm, patient, inviting learning tone
+#   educational-alt   — alternate take of educational
+#   tutorial          — lo-fi background, stays out of voiceover's way
+#   tutorial-alt      — alternate take of tutorial
+#
+# Flags (all optional):
+#   --mood=<name>     pick a preset from the library (default: tech)
+#   --music=<path>    override with your own audio file (wins over --mood)
+#   --out=<path>      output path (default: <input-basename>-bgm.mp4)
+#
+# Legacy positional form still works: bash add-music.sh in.mp4 music.mp3 out.mp4
+#
+# Behavior:
+#   - Music is trimmed to match video duration
+#   - 0.3s fade in, 1.0s fade out (avoids hard cuts)
+#   - Video stream copied (no re-encode), audio AAC 192k
+#
+# Examples:
+#   bash add-music.sh my.mp4                              # default: tech mood
+#   bash add-music.sh my.mp4 --mood=ad                    # switch mood

+## Voice Pillars
+
+### 1. เป็นกันเอง (Friendly)
+- **What it means**: พูดเหมือนเพื่อนช่วยเพื่อน ไม่ทางการเกินไป
+- **Example**: "มาเริ่มกันเลย! ไม่ต้องรอให้พร้อม 100%"
+- **Avoid**: ภาษาทางการแบบเอกสารราชการ
+
+### 2. น่าเชื่อถือ (Trustworthy)
+- **What it means**: ให้ข้อมูลที่ถูกต้อง มีหลักฐานรองรับ
+- **Example**: "จากการทดสอบ เราพบว่า..."
+- **Avoid**: อ้างอิงไม่มีแหล่งที่มา
+
+### 3. มีประโยชน์ (Helpful)
+- **What it means**: มุ่งให้ค่ากับผู้อ่าน ช่วยแก้ปัญหา
+- **Example**: "ทำตามขั้นตอนนี้ คุณจะได้..."
+- **Avoid**: ขายของเกินไปโดยไม่ให้คุณค่า
+
+---
+
+## Tone Guidelines
+
+### General Tone
+
+พูดแบบเพื่อนที่หวังดี อธิบายเรื่องยากให้ง่าย
+
+### By Content Type

+### Value Propositions
+
+**For Beginners**: เริ่มต้นง่าย ไม่ต้องมีพื้นฐานก็ทำได้
+
+**For Professionals**: เครื่องมือครบ จบในที่เดียว
+
+---
+
+## Writing Examples
+
+### Excellent Voice ✅
+
+"มาเริ่ม podcast กันเลย! ไม่ต้องรอให้พร้อม 100% แค่มีไอเดียดีๆ กับไมค์หนึ่งอัน คุณก็เริ่มต้นได้แล้ว ส่วนเรื่องเทคนิคที่เหลือ เราช่วยคุณเอง"
+
+**Why this works**:
+- เป็นกันเอง
+- ให้กำลังใจ
+- ไม่ข่มขู่ด้วยความยาก
+
+### Not Our Voice ❌
+
+"การดำเนินการสร้าง podcast จำเป็นต้องมีการเตรียมการอย่างรอบคอบและใช้อุปกรณ์ที่มีคุณภาพสูง"
+
+**Why this fails**:
+- เป็นทางการเกินไป
+- ดูน่ากลัว
+- ไม่เป็นมิตร

+    ///
+    /// Feel: Clean, structured, slightly more open than IEEE.
+    /// Best for: ACM conference proceedings (SIGCHI, SIGMOD, SIGGRAPH, etc.),
+    /// ACM journal submissions.
+    ///
+    /// Design rationale (all values from acmart.cls and ACM Author Guide):
+    /// - US Letter, 1.25in top/bottom, 0.75in L/R: more generous vertical margins
+    ///   than IEEE, giving a less cramped appearance.
+    /// - Two columns with 0.33in (480 DXA) gutter: slightly wider than IEEE's
+    ///   0.25in, providing better visual separation between columns.
+    /// - 9pt Times New Roman body (sz=18): ACM's standard body size. The original
+    ///   acmart uses Linux Libertine, but TNR is the accessible fallback specified
+    ///   in the ACM Author Guide for systems without Libertine.
+    /// - 14.4pt bold title, flush left (sz=29): ACM titles are bold and left-aligned,
+    ///   unlike IEEE's centered unbolded titles. The 14.4pt size (1.6x body) creates
+    ///   strong but not overwhelming hierarchy.
+    /// - H1: 10pt bold ALL CAPS, flush left, arabic numbered (sz=20). ALL CAPS at
+    ///   body size with bold creates definitive section breaks.
+    /// - H2: 10pt bold title case, flush left (sz=20). Bold without caps is the
+    ///   minimal step down from H1.
+    /// - H3: 10pt bold italic, flush left (sz=20). Adding italic distinguishes
+    ///   from H2 while maintaining the same weight.
+    /// - Single spacing: required for ACM camera-ready format.
+    /// - First-line indent ~10pt (200 DXA): slightly larger than IEEE's 0.125in,
+    ///   matching ACM's convention of a roughly 1em indent at 9pt.
+    /// - Captions: 8pt (sz=16) — consistent with ACM figure/table caption style.
+    /// - References: 7.5pt (sz=15) — ACM uses a smaller font for the bibliography
+    ///   to maximize space for content.

+    /// - Line spacing: Double-spaced throughout, including block quotes and Works Cited.
+    /// - Paragraph indent: 0.5 inch first-line indent for body paragraphs.
+    /// - Title: Centered, same size as body text (12pt), NOT bold, italic, or underlined.
+    ///   MLA eschews visual hierarchy — the title is distinguished only by centering.
+    /// - No mandatory heading system. If headings are used, they should be simple and
+    ///   consistent. MLA does not prescribe heading levels like APA does.
+    /// - Running header: Author's last name and page number, flush right, 0.5 inch from top.
+    /// - First-page header block: Student's name, instructor's name, course title, and
+    ///   date — upper left, double-spaced, NO extra spacing.
+    /// - Works Cited: title "Works Cited" centered (not bold), entries have hanging indent
+    ///   of 0.5 inch (first line flush left, subsequent lines indented).
+    /// - No title page required (unless specifically requested by instructor).
+    ///
+    /// Design rationale:
+    /// - MLA's aesthetic is deliberately plain — the writing is the content.
+    /// - No bold headings, no size variation, no decorative elements.
+    /// - The only structural markers are centering (title, Works Cited label)
+    ///   and indentation (paragraphs, hanging indent for citations).
+    /// - This uniformity reflects MLA's roots in literary studies, where the

+// ListAndNumberingSamples.cs — OpenXML numbering system deep dive
+// ============================================================================
+// OpenXML list/numbering architecture (3 layers):
+//
+//   1. AbstractNum — defines the numbering FORMAT (bullet chars, number formats,
+//      indentation, fonts). Contains Level elements (0-8) for multi-level lists.
+//
+//   2. NumberingInstance (Num) — a concrete "instance" that references an
+//      AbstractNum. Multiple paragraphs share the same NumId to form one list.
+//      LevelOverride on a NumberingInstance can restart numbering.
+//
+//   3. NumberingProperties on Paragraph — links a paragraph to a NumberingInstance
+//      via NumId + Level (ilvl). This is what makes a paragraph a list item.
+//
+// CRITICAL RULES:
+//   - In the Numbering root element, ALL AbstractNum elements MUST appear
+//     BEFORE any NumberingInstance (Num) elements. Violating this order causes
+//     Word to report corruption.
+//   - LevelText uses %1, %2, %3 etc. as placeholders for the current value
+//     at each level. %1 = level 0's value, %2 = level 1's value, etc.
+//   - NumberingSymbolRunProperties (rPr inside Level) sets the font for the
+//     bullet character or number. Without it, the bullet may render in the
+//     paragraph's font, which can produce wrong glyphs.
+//   - IsLegalNumberingStyle on a Level forces "legal" flat numbering
+//     (e.g., "1.1.1" instead of outline style) regardless of heading level.
+//
+// Storage: Numbering definitions live in numbering.xml, accessed via
+//   NumberingDefinitionsPart on the MainDocumentPart.

+ *   2. print 媒体下外层 `!important` 压不住 shadow DOM 规则
+ *   3. 结果：PDF 永远只有 1 页（active 那张）
+ *
+ * 解决方案：
+ *   打开 HTML 后，用 page.evaluate 把所有 section 从 deck-stage slot 拔出来，

+formula_check.py — Static formula validator for xlsx files.
+
+Usage:
+    python3 formula_check.py <input.xlsx>
+    python3 formula_check.py <input.xlsx> --json          # machine-readable output
+    python3 formula_check.py <input.xlsx> --report        # standardized validation report (JSON)
+    python3 formula_check.py <input.xlsx> --report -o out # report to file
+    python3 formula_check.py <input.xlsx> --sheet Sales   # limit to one sheet
+    python3 formula_check.py <input.xlsx> --summary       # error counts only, no details
+
+What it checks:
+1. Error-value cells: <c t="e"><v>#REF!</v></c> — all 7 Excel error types
+2. Broken cross-sheet references: formula references a sheet not in workbook.xml
+3. Broken named-range references: formula references a name not in workbook.xml <definedNames>
+4. Shared formula integrity: shared formula primary cell exists and has formula text
+5. Missing <v> on t="e" cells (malformed XML)
+
+Checks NOT performed (require dynamic recalculation):
+- Runtime errors that only appear after formulas execute (#DIV/0! on empty denominator, etc.)
+  -> Use libreoffice_recalc.py + re-run formula_check.py for dynamic validation
+
+Exit code:
+    0 — no errors found
+    1 — errors detected (or file cannot be opened)

+ * html2pptx - Convert HTML slide to pptxgenjs slide with positioned elements
+ *
+ * USAGE:
+ *   const pptx = new pptxgen();
+ *   pptx.layout = 'LAYOUT_16x9';  // Must match HTML body dimensions
+ *
+ *   const { slide, placeholders } = await html2pptx('slide.html', pptx);
+ *   slide.addChart(pptx.charts.LINE, data, placeholders[0]);
+ *
+ *   await pptx.writeFile('output.pptx');
+ *
+ * FEATURES:
+ *   - Converts HTML to PowerPoint with accurate positioning
+ *   - Supports text, images, shapes, and bullet lists
+ *   - Extracts placeholder elements (class="placeholder") with positions
+ *   - Handles CSS gradients, borders, and margins
+ *
+ * VALIDATION:
+ *   - Uses body width/height from HTML for viewport sizing
+ *   - Throws error if HTML dimensions don't match presentation layout
+ *   - Throws error if content overflows body (with overflow details)
+ *
+ * RETURNS:
+ *   { slide, placeholders } where placeholders is an array of { id, x, y, w, h }
