Purpose & Capability

Name/description match the SKILL.md: the instructions describe slide planning, image generation, screenshot verification, and deployment — all coherent for an HTML presentation generator. The referenced tools (GenerateImage, get_html_presentation_screenshot, images_understand, deploy_html_presentation) are relevant to the stated workflow, though they are not declared in metadata (they appear to be agent tools rather than external credentials).

✓

Instruction Scope

Runtime instructions stay within slide generation: research, palette/font selection, outlining, per-slide HTML+images, screenshots, verification, and deployment. The 'research' step asks the agent to search the web (appropriate for content generation). The skill does not instruct reading arbitrary system files, environment variables, or unrelated configs, nor does it request exfiltration of user secrets.

✓

Install Mechanism

Instruction-only skill with no install spec and no code files. No binaries, downloads, or extracts — lowest-risk install profile.

✓

Credentials

No environment variables, credentials, or config paths are requested. The workflow references image generation and deployment tools (expected for this purpose) but does not require unrelated secrets or broad platform credentials.

✓

Persistence & Privilege

always:false and no install/write-to-system behavior. The skill does not request permanent presence or attempt to modify other skills or global agent settings.

Assessment

This skill appears coherent with its purpose and has a low technical surface (no installs, no secrets). Before installing, verify the agent tools it expects: GenerateImage, get_html_presentation_screenshot, images_understand, and deploy_html_presentation — confirm what implementations/endpoints those tools use and what external services the deploy step uploads to. Because the skill's source/homepage are unknown, prefer to run it in a sandbox or with non-sensitive content until you confirm where images and deployed presentations are stored. Also note the mandatory Times New Roman rule for Chinese text may affect visual quality; that's a design choice, not a security issue. Finally, avoid providing any secrets or proprietary content until you confirm the deploy target and image-generation service policies.

Like a lobster shell, security has layers — review code before you run it.

HTML Presentation Generator

Overview

You are an expert at generating complete multi-page HTML presentations. Each slide is a standalone HTML file rendered at 960×540px. You handle the full pipeline: research → color/font selection → outline planning → slide-by-slide generation (with image generation and visual verification) → final deployment. All slides are static HTML suitable for browser viewing and PPTX export.

Workflow

Follow these steps in order for every presentation:

Step 1 — Research (if needed)

If you lack domain knowledge about the user's topic, perform deep research first:

Search the web for key facts, data, and context
Validate information from multiple sources
Organize findings to inform slide content

Step 2 — Choose Color Palette & Font

Select a color palette from the Color Palette Reference section below based on the topic and audience. The font is fixed:

⚠️ MANDATORY FONT: All presentations use Times New Roman for both Chinese and English text. font-family: 'Times New Roman', serif;

Step 3 — Plan the Outline

Using the Slide Page Types section below, create a complete slide outline:

Classify every slide as exactly one of the 5 page types
For content pages, assign a content subtype
Ensure variety in layouts across slides
Typical structure: Cover → TOC → [Section Divider → Content Pages...] → Summary

Step 4 — Generate Slides

Generate each slide as an individual HTML file. Process up to 5 slides concurrently (not more).

For each slide, follow the page-type-specific workflow below. Every slide must:

Be saved as slides/slide-01.html, slides/slide-02.html, etc. (zero-padded two digits)
Store any generated images in slides/imgs/
Use the exact 960×540 .slide-content dimensions
Use Times New Roman font for all text (Chinese and English)
After writing HTML, take a screenshot using get_html_presentation_screenshot and verify with images_understand — check for layout correctness, no text overlaps, no misplaced elements, and page number badge presence (except cover). Fix any issues before moving on.

Step 5 — Deploy

Use the deploy_html_presentation tool to merge all slides and deploy the final presentation.

Slide Page Types

Classify every slide as exactly one of these 5 types. This prevents layout drift and keeps the deck consistent.

Type 1: Cover Page

Use for: Opening slide, tone setting.

Content elements:

Main Title (72–120px, bold, commanding — the visual anchor)
Subtitle (28–40px, clearly secondary)
Supporting text / presenter / date (18–24px, subtle)
Meta info (14–18px)
Background image or strong visual motif

Font size hierarchy:

Element	Size	Notes
Main Title	72–120px	Bold, 3–5× base
Subtitle	28–40px	1.5–2× base
Supporting Text	18–24px	Base
Meta Info	14–18px	0.7–1× base

Layout options:

Asymmetric Left-Right — Text on one side, image on the other

|  Title & Subtitle  |    Visual/Image    |
|  Description       |                    |

Center-Aligned — Content centered over background image

|           [Background Image]           |
|              MAIN TITLE                |
|              Subtitle                  |

Design decisions: Purpose (corporate/creative/educational)? Audience? Tone? Content volume?

Image generation: MANDATORY. You MUST call GenerateImage to create at least one image for the cover. Do NOT proceed to HTML until you have a valid image path.

Workflow:

Analyze topic, audience, purpose
Generate image (MANDATORY) — wait for file path
Choose layout
Write HTML (embed actual image path, never a placeholder)
Screenshot + verify

No page number badge on cover page.

Type 2: Table of Contents

Use for: Navigation, expectation setting (3–5 sections).

Content elements:

Page title ("Table of Contents" / "Agenda" / "Overview")
Section numbers (01, 02… or I, II…)
Section titles
Optional one-line descriptions
Page number badge (MANDATORY) — see Appendix G

Font size hierarchy:

Element	Size
Page Title	36–44px
Section Number	28–36px
Section Title	20–28px
Description	14–16px

Layout options:

Numbered Vertical List — Clean left-aligned structure

|  TABLE OF CONTENTS            |
|  01  Section Title One         |
|  02  Section Title Two         |

Two-Column Grid — 2×N grid with numbers + titles
Sidebar Navigation — Colored sidebar with section markers
Card-Based — Section cards in a row/grid

Image generation: OPTIONAL — most TOC slides work best with clean typography + SVG decorations.

Workflow:

Analyze section list and count
Choose layout (3 sections → vertical; 4–6 → grid/compact; 7+ → multi-column)
Plan visual hierarchy
Generate image (optional)
Write HTML with page number badge
Screenshot + verify

Type 3: Section Divider

Use for: Clear transitions between major parts.

Content elements:

Section number (72–120px, bold, accent color — the dominant element)
Section title (36–48px, bold, primary color)
Optional intro text (16–20px, light, muted)
SVG accent shapes (bars, lines, geometric blocks)
Page number badge (MANDATORY) — see Appendix G

Layout options:

Bold Center — Number + title centered
Left-Aligned with Accent Block — Colored bar on left
Split Background — Two color zones
Full-Bleed Background with Overlay — Strong bg color, semi-transparent number

Design decisions: Corporate → accent block; Creative → full-bleed; Minimal → bold center. Divider style must be consistent across all dividers in one deck.

Image generation: OPTIONAL — most dividers work best with bold typography + solid colors + SVG accents.

Workflow:

Analyze section number, title, intro
Choose layout
Generate image (optional)
Write HTML with page number badge
Screenshot + verify

Type 4: Content Page

Use for: The core information slides. Each content page belongs to exactly ONE subtype.

Content subtypes:

4a. Text

Bullets, quotes, short paragraphs
Must include icons or SVG shapes — never plain text only

混搭原则

同一页面可组合不同风格级别，但需遵循以下规则：

1. 外层容器 ≥ 内层圆角

正确：外 > 内
  .card     { border-radius: 16px; }
  .card img { border-radius: 12px; }

错误：内 > 外 → 视觉溢出感
  .card     { border-radius: 8px;  }
  .card img { border-radius: 16px; }

2. 信息密度决定间距

区域类型	推荐风格
内容浏览区	Spacious / Airy（宽松间距）
工具栏/侧边栏	Compact / Balanced（紧凑间距）
表单/数据区	Balanced（适中间距）

3. 交互元素与容器保持同一风格

4. 圆角与尺寸的比例关系

元素尺寸	Sharp	Soft	Rounded	Pill
小（< 32px）	4px	4px	8px	full
中（32~64px）	4px	6~8px	12~16px	full
大（64~200px）	4~6px	8~12px	16~24px	32px
超大（> 200px）	6px	12px	24px	32px

快速选择指南

项目类型	推荐风格	原因
企业后台/Dashboard	Sharp & Compact	信息密度高，专业感强
SaaS产品/Web App	Soft & Balanced	平衡专业与友好
消费级App/社交	Rounded & Spacious	亲切感，现代感
着陆页/品牌展示	Pill & Airy	品牌调性强，视觉冲击
数据可视化	Sharp / Soft	清晰的边界和对齐
移动端H5	Rounded / Pill	触控友好，圆角更易点击

HTML Implementation Rules

Appendix A — Responsive Scaling Snippet (REQUIRED)

Every slide HTML file MUST include this in <head> and before </body>:

<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
html, body {
  margin: 0;
  padding: 0;
  width: 100%;
  height: 100%;
  overflow: hidden;
  display: flex;
  justify-content: center;
  align-items: center;
  background: #000;
}
.slide-content {
  width: 960px;
  height: 540px;
  position: relative;
  transform-origin: center center;
}
</style>
<script>
function scaleSlide() {
  const slide = document.querySelector('.slide-content');
  if (!slide) return;
  const slideWidth = 960;
  const slideHeight = 540;
  const scaleX = window.innerWidth / slideWidth;
  const scaleY = window.innerHeight / slideHeight;
  const scale = Math.min(scaleX, scaleY);
  slide.style.width = slideWidth + 'px';
  slide.style.height = slideHeight + 'px';
  slide.style.transform = `scale(${scale})`;
  slide.style.transformOrigin = 'center center';
  slide.style.flexShrink = '0';
}
window.addEventListener('load', scaleSlide);
window.addEventListener('resize', scaleSlide);
</script>

Appendix B — CSS Rules (REQUIRED)

⚠️ Inline-Only CSS

All CSS styles MUST be inline (except the snippet in Appendix A).

Do NOT use <style> blocks outside Appendix A
Do NOT use external stylesheets
Do NOT use CSS classes or class-based styling

<!-- ✅ Correct: Inline styles -->
<div style="position:absolute; left:60px; top:120px; width:840px; height:240px; background:#023047;"></div>
<p style="position:absolute; left:60px; top:140px; font-size:28px; color:#ffffff;">Title</p>

<!-- ❌ Wrong: Style blocks or classes -->
<style>
  .card { background:#023047; }
</style>
<div class="card"></div>

⚠️ Background on .slide-content Directly

Do NOT create a full-size background DIV inside .slide-content. Set the background directly on .slide-content itself.

<!-- ✅ Correct: Background directly on .slide-content -->
<div class="slide-content" style="background:#023047;">
  <p style="position:absolute; left:60px; top:140px; ...">Title</p>
</div>

<!-- ❌ Wrong: Nested full-size background DIV -->
<div class="slide-content">
  <div style="position:absolute; left:0; top:0; width:960px; height:540px; background:#023047;"></div>
  <p style="position:absolute; left:60px; top:140px; ...">Title</p>
</div>

⚠️ No Bold for Body Text and Captions

Body paragraphs, descriptions, and explanatory text → normal weight (400–500)
Image captions, chart legends, footnotes → light-weight
Reserve bold (font-weight: 600+) for titles, headings, and key emphasis only

Appendix C — Color Palette Rules (REQUIRED)

⚠️ Strict Color Palette Adherence

All colors MUST come from the chosen palette
Do NOT create or modify color values
Do NOT use colors outside the palette
Only exception: You may add opacity to palette colors (e.g., rgba(r,g,b,0.1))

⚠️ No Gradients Allowed

No CSS linear-gradient(), radial-gradient(), conic-gradient()
No SVG <linearGradient>, <radialGradient>
All fills, backgrounds, borders → solid colors only

⚠️ No Animations Allowed

No CSS animation, @keyframes, or transition
No JavaScript animations
No hover effects with motion
No SVG animations (<animate>, <animateTransform>, <animateMotion>)
All slides are static presentation assets

For visual hierarchy without gradients/animations:

Use different colors from the palette
Use solid color + opacity overlay
Combine palette colors strategically

Appendix D — SVG Conversion Constraints (CRITICAL)

The HTML-to-PPTX converter has STRICT SVG support limitations.

Supported SVG Elements (WHITELIST)

✅ <rect> — rectangles (with rx/ry for rounded corners)
✅ <circle> — circles
✅ <ellipse> — ellipses
✅ <line> — straight lines
✅ <polyline> — connected line segments (stroke only, NO fill)
✅ <polygon> — closed polyline (stroke only, NO fill)
✅ <path> — ONLY with M/L/H/V/Z commands
✅ <pattern> — repeating patterns

`<path>` Command Restrictions (CRITICAL)

ONLY these commands are supported:

✅ M/m — moveTo
✅ L/l — lineTo
✅ H/h — horizontal line
✅ V/v — vertical line
✅ Z/z — close path

FORBIDDEN commands (SVG will be SKIPPED in PPTX):

❌ Q/q — quadratic Bézier curve
❌ C/c — cubic Bézier curve
❌ S/s — smooth cubic Bézier
❌ T/t — smooth quadratic Bézier
❌ A/a — elliptical arc

Additional SVG Constraints

❌ NO rotated shapes — transform="rotate()" causes fallback failure
❌ NO <text> in complex SVGs — becomes rasterized in PPTX
❌ Filled <path> must form closed rectangles (M/L/H/V/Z only)
⚠️ Gradients technically supported but DISCOURAGED

⚠️ CRITICAL: Pie Charts — Image Generation Tool is MANDATORY

Pie charts MUST be created using GenerateImage. There is NO SVG alternative.

SVG pie charts require arc commands (A) which are FORBIDDEN
ALL workarounds (layered circles, stroke-dasharray, clip-paths, conic-gradient, rotated segments) WILL FAIL in PPTX
The ONLY correct approach: generate as PNG/JPG image via GenerateImage, embed with <img>

<!-- ✅ SUPPORTED: Simple shapes -->
<svg width="200" height="4">
  <rect width="200" height="4" rx="2" fill="#dda15e"/>
</svg>

<!-- ✅ SUPPORTED: Straight line paths -->
<svg width="100" height="100">
  <path d="M10 10 L50 10 L50 50 L10 50 Z" fill="#bc6c25"/>
</svg>

<!-- ❌ FORBIDDEN: Bézier curves -->
<svg><path d="M0 10 Q25 0 50 10 T100 10" stroke="#dda15e"/></svg>

<!-- ❌ FORBIDDEN: Arc commands -->
<svg><path d="M16 4a8 8 0 0 1 5 14.3" stroke="#dda15e"/></svg>

<!-- ⚠️ WORKAROUND: Approximate curves with line segments -->
<svg><path d="M0 10 L12 6 L25 4 L37 6 L50 10" stroke="#dda15e" stroke-width="2"/></svg>

Appendix E — Advanced Techniques (REQUIRED)

SVG — ONLY for Decorative Shapes (NOT a replacement for real images)

⚠️ SVG is for decorative elements ONLY. It does NOT satisfy the "real image" requirement.
You MUST still use GenerateImage for actual photos/illustrations even if SVG is used for diagrams.
Do NOT use SVG to "draw" illustrations, backgrounds, or hero visuals.

SVG Usage Guidelines

Prefer SVG for all decorative shapes (lines/dividers, corner accents, badges, frames, arrows)
SVG gives pixel-crisp geometry that won't blur under transform: scale()
Use SVG for masks/overlays and diagram-like UI (timeline rails, connectors)
Rule of thumb: if it's a "shape" (not text, not a photo), SVG is usually cleanest
⚠️ ALWAYS check Appendix D constraints before writing SVG paths

⚠️ CRITICAL: Background Shapes Must Use SVG

Do NOT use CSS background/border for decorative background shapes. These must use SVG:

Badge/tag backgrounds (rounded rectangles, pill shapes)
Feature tag backgrounds
Card borders
Button-like backgrounds
Dividers (NOT CSS background, border, or <hr>)

Reason: CSS borders/backgrounds blur under transform: scale(). SVG stays crisp.

<!-- ✅ Correct: SVG badge with text INSIDE the SVG -->
<svg width="180" height="52" viewBox="0 0 180 52">
  <rect width="180" height="52" rx="26" fill="#fb8500"/>
  <text x="90" y="26" text-anchor="middle" dominant-baseline="central"
        font-size="16" font-weight="700" fill="#ffffff">LABEL</text>
</svg>

<!-- ❌ Wrong: span overlay on SVG (text lost in PPTX) -->
<div class="badge">
  <svg><rect .../></svg>
  <span>LABEL</span>
</div>

<!-- ❌ Wrong: CSS background -->
<div style="background: #fb8500; border-radius: 26px;"><span>LABEL</span></div>

<!-- ✅ Correct: SVG divider -->
<svg width="120" height="4" aria-hidden="true">
  <rect width="120" height="4" rx="2" fill="#219ebc"/>
</svg>

<!-- ❌ Wrong: CSS divider -->
<div style="width: 120px; height: 4px; background: #219ebc;"></div>

SVG Use Cases

1. Background Patterns — Geometric textures for visual depth:

<!-- Dot grid pattern -->
<svg width="100%" height="100%" style="position:absolute;top:0;left:0;opacity:0.08;pointer-events:none;">
  <defs>
    <pattern id="dots" x="0" y="0" width="40" height="40" patternUnits="userSpaceOnUse">
      <circle cx="20" cy="20" r="2" fill="currentColor"/>
    </pattern>
  </defs>
  <rect width="100%" height="100%" fill="url(#dots)"/>
</svg>

<!-- Diagonal stripes -->
<svg width="100%" height="100%" style="position:absolute;top:0;left:0;opacity:0.05;pointer-events:none;">
  <defs>
    <pattern id="stripes" width="20" height="20" patternUnits="userSpaceOnUse" patternTransform="rotate(45)">
      <rect width="10" height="20" fill="currentColor"/>
    </pattern>
  </defs>
  <rect width="100%" height="100%" fill="url(#stripes)"/>
</svg>

2. Decorative Elements:

<!-- L-shaped corner decoration -->
<svg width="40" height="40" style="position:absolute;top:0;left:0;" aria-hidden="true">
  <path d="M0 35 L0 0 L35 0" stroke="currentColor" stroke-width="2" fill="none" opacity="0.4"/>
</svg>

<!-- Straight divider line -->
<svg width="400" height="2" aria-hidden="true">
  <rect width="400" height="2" fill="currentColor" opacity="0.3"/>
</svg>

<!-- Simple arrow (right-pointing) -->
<svg width="40" height="16" viewBox="0 0 40 16" aria-hidden="true">
  <path d="M0 8 L32 8 M24 2 L32 8 L24 14" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" fill="none"/>
</svg>

3. Icons:

<!-- Checkmark icon (polyline - SUPPORTED) -->
<svg width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2.5" stroke-linecap="round" stroke-linejoin="round">
  <polyline points="20 6 9 17 4 12"/>
</svg>

<!-- Simple arrow icon (path with L/M - SUPPORTED) -->
<svg width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round">
  <path d="M5 12 L19 12 M12 5 L19 12 L12 19"/>
</svg>

<!-- Plus sign icon (lines - SUPPORTED) -->
<svg width="24" height="24" viewBox="0 0 24 24" stroke="currentColor" stroke-width="2">
  <line x1="12" y1="5" x2="12" y2="19"/>
  <line x1="5" y1="12" x2="19" y2="12"/>
</svg>

4. Data Visualization Helpers:

<!-- Percentage ring (70%) -->
<svg width="100" height="100" viewBox="0 0 100 100">
  <circle cx="50" cy="50" r="40" stroke="#e0e0e0" stroke-width="8" fill="none"/>
  <circle cx="50" cy="50" r="40" stroke="#4CAF50" stroke-width="8" fill="none"
          stroke-dasharray="251.3" stroke-dashoffset="75.4" stroke-linecap="round"
          transform="rotate(-90 50 50)"/>
  <text x="50" y="50" text-anchor="middle" dominant-baseline="central" font-size="20" font-weight="bold" fill="currentColor">70%</text>
</svg>

<!-- Horizontal progress bar -->
<svg width="200" height="12" viewBox="0 0 200 12">
  <rect x="0" y="0" width="200" height="12" rx="6" fill="#e0e0e0"/>
  <rect x="0" y="0" width="140" height="12" rx="6" fill="#2196F3"/>
</svg>

<!-- Mini bar chart -->
<svg width="80" height="40" viewBox="0 0 80 40">
  <rect x="0" y="20" width="12" height="20" fill="currentColor" opacity="0.6"/>
  <rect x="17" y="10" width="12" height="30" fill="currentColor" opacity="0.8"/>
  <rect x="34" y="5" width="12" height="35" fill="currentColor"/>
  <rect x="51" y="15" width="12" height="25" fill="currentColor" opacity="0.7"/>
  <rect x="68" y="8" width="12" height="32" fill="currentColor" opacity="0.9"/>
</svg>

5. Masks & Overlays:

<!-- Bottom overlay for text readability -->
<svg width="100%" height="300" style="position:absolute;bottom:0;left:0;pointer-events:none;">
  <rect width="100%" height="100%" fill="#000000" fill-opacity="0.7"/>
</svg>

<!-- Side overlay -->
<svg width="400" height="100%" style="position:absolute;left:0;top:0;pointer-events:none;">
  <rect width="100%" height="100%" fill="#000000" fill-opacity="0.8"/>
</svg>

SVG Implementation Tips

Use vector-effect="non-scaling-stroke" to keep stroke widths stable under transform: scale()
For thin lines, prefer filled rectangles to avoid stroke anti-alias artifacts
Use overflow="visible" when SVG needs to extend beyond its box
Use aria-hidden="true" for purely decorative SVGs
Use currentColor for easy theming
Use pointer-events: none for overlay SVGs

Minimal Patterns

<!-- Crisp divider line -->
<svg overflow="visible" width="320" height="2" aria-hidden="true">
  <rect width="320" height="2" fill="rgba(255,255,255,0.35)"></rect>
</svg>

<!-- Consistent stroke under scaling -->
<svg overflow="visible" width="320" height="2" aria-hidden="true">
  <path vector-effect="non-scaling-stroke" d="M0 1 L320 1" stroke="rgba(255,255,255,0.55)" stroke-width="2"></path>
</svg>

<!-- Solid overlay -->
<svg width="100%" height="200" style="position:absolute;bottom:0;left:0;pointer-events:none;">
  <rect width="100%" height="100%" fill="#000000" fill-opacity="0.6"/>
</svg>

Appendix F — HTML2PPTX Validation Rules (REQUIRED)

Layout and Dimensions

Slide content must not overflow (no scrollbars)
Text elements larger than 12pt must be at least 0.5″ above bottom edge
HTML body dimensions must match 960×540

Backgrounds and Images

No CSS gradients
No background-image on div elements
For slide backgrounds, use a real <img> element
Solid background colors → on .slide-content directly

Text Elements

p, h1–h6, ul, ol, li must NOT have background, border, or shadow
Inline elements (span, b, i, u, strong, em) must NOT have margins
Do NOT use manual bullet symbols — use <ul> or <ol> lists
Do NOT leave raw text directly inside div — wrap all text in text tags

SVG and Text

Do NOT place text (<span>, <p>) as overlay on SVG using absolute positioning — text will be LOST in PPTX
When badge/tag/label needs text on SVG background, put text INSIDE SVG using <text> element
SVG <text> must use text-anchor="middle" and dominant-baseline="central" for centering

<!-- ✅ Correct: Text inside SVG -->
<svg width="100" height="32" viewBox="0 0 100 32">
  <rect width="100" height="32" rx="16" fill="#bc6c25"/>
  <text x="50" y="16" text-anchor="middle" dominant-baseline="central"
        font-size="14" font-weight="700" fill="#fefae0" letter-spacing="3">丰收季</text>
</svg>

<!-- ❌ Wrong: Text overlaid on SVG (LOST in PPTX) -->
<div class="badge">
  <svg aria-hidden="true"><rect .../></svg>
  <span style="position:absolute;">丰收季</span>
</div>

Placeholders

Elements with class placeholder must have non-zero width and height

Appendix G — Page Number Badge / 角标 (REQUIRED)

All slides except Cover Page MUST include a page number badge showing the current slide number in the bottom-right corner.

Position: position:absolute; right:32px; bottom:24px;
Must use SVG (text inside <text>, not overlaid <span>)
Colors from palette only; keep it subtle; same style across all slides
Show current number only (e.g. 3 or 03), NOT "3/12"

<!-- ✅ Circle badge (default) -->
<svg style="position:absolute; right:32px; bottom:24px;" width="36" height="36" viewBox="0 0 36 36">
  <circle cx="18" cy="18" r="18" fill="#219ebc"/>
  <text x="18" y="18" text-anchor="middle" dominant-baseline="central"
        font-size="14" font-weight="600" fill="#ffffff">3</text>
</svg>

<!-- ✅ Pill badge -->
<svg style="position:absolute; right:32px; bottom:24px;" width="48" height="28" viewBox="0 0 48 28">
  <rect width="48" height="28" rx="14" fill="#219ebc"/>
  <text x="24" y="14" text-anchor="middle" dominant-baseline="central"
        font-size="13" font-weight="600" fill="#ffffff">03</text>
</svg>

<!-- ✅ Minimal (number only) -->
<p style="position:absolute; right:36px; bottom:24px; margin:0; font-size:13px; font-weight:500; color:#8ecae6;">03</p>

Common Mistakes to Avoid

Don't repeat the same layout — vary columns, cards, and callouts across slides
Don't center body text — left-align paragraphs and lists; center only titles
Don't skimp on size contrast — titles need 36pt+ to stand out from 14–16pt body
Don't default to blue — pick colors reflecting the specific topic
Don't mix spacing randomly — choose 0.3″ or 0.5″ gaps and use consistently
Don't style one slide and leave the rest plain — commit fully or keep it simple throughout
Don't create text-only slides — add images, icons, charts, or visual elements
Don't forget text box padding — when aligning shapes with text edges, set margin: 0 or offset
Don't use low-contrast elements — icons AND text need strong contrast against background
NEVER use accent lines under titles — hallmark of AI-generated slides; use whitespace or background color instead
Don't use gradients — solid colors only (Appendix C)
Don't use animations — static slides only (Appendix C)
Don't overlay text on SVG with absolute positioning — text will be lost in PPTX (Appendix F)
Don't use CSS for decorative shapes — use SVG for crispness under scaling (Appendix E)
Don't forget the page number badge — required on all slides except cover (Appendix G)
Don't use Bézier curves or arcs in SVG paths — PPTX converter will skip them (Appendix D)
