## V. Page Structure

### Common Navigation Bar (y=0 to 100)

- **Top Blue Bar**: 8px height, deep blue gradient.
- **Logo Area**: Fixed at upper-right corner with a white backing plate.
- **Title Group**: Upper-left corner using **"Tag Style"** design, simulating engineering drawing labels.

---

## VI. Page Types

### 1. Cover Page (01_cover.svg)
- **Visual Focus**: **"Foundation"** concept. Heavy deep blue supporting the bottom, transparent top.
- **Background**: Overlaid with precision **"Geo Grid"** (latitude-longitude grid), symbolizing global presence.
- **Layout**: Center-symmetric layout, projecting state-owned enterprise gravitas.

### 2. Table of Contents (02_toc.svg)
- **Layout**: **"Milestones"** style. Horizontal timeline or connected cards, representing project progression.
- **Elements**: Connection lines and node dots, simulating circuits or pipeline networks.

### 3. Chapter Page (02_chapter.svg)
- **Background**: Deep blue tech gradient; large whitespace on the right for perspective grid.
- **Numbers**: Giant outlined numbers (Stroke Only) — not just chapter numbers, but part of the architectural structure.

### 4. Content Page (03_content.svg)
- **Layout**: **"Console"** style. Orderly top navigation bar, maximized content area.
- **Details**: **"Corner Marks"** added at all four corners for a precision engineering feel.

### 5. Ending Page (04_ending.svg)
- **Background**: Echoes the cover's "Foundation" structure.
- **Elements**: Reinforces "win-win cooperation" concept with QR code / contact information displayed in zones.

## VII. SVG Page Roster

| File | Role | Description |
|------|------|-------------|
| `01_cover.svg` | cover | Title slide; brand/project name + presenter + date |
| `02_chapter.svg` | chapter | Chapter divider page (large number + chapter title) |
| `02_toc.svg` | toc | Table of contents listing major sections |
| `03_content.svg` | content | Main content page; body of the deck |
| `04_ending.svg` | ending | Closing/thank-you page |

## VIII. Layout Patterns (Recommended)

### 1. Tech Cards
- Cards with subtle borders and a glowing effect.
- Ideal for showcasing key technical indicators or innovation achievements.

### 2. Dashboard
- Combined layout of charts and key data.
- Uses Tech Blue as the primary chart color.

### 3. Blueprint
- Leverages the Geo Grid background to explain complex structures through lines and annotations.

## IX. Spacing Guidelines

| Property       | Value | Description              |
| -------------- | ----- | ------------------------ |
| **Base Unit**  | 4px   | Precision design uses a 4px grid |
| **Module Gap** | 40px  | Generous spacing for breathing room |
| **Card Gap**   | 20px  | Compact yet clear spacing |
| **Inner Padding** | 32px | Distance between content and border |

---

## X. SVG Technical Constraints

### Mandatory Rules

1. **Gradients**: Use `<linearGradient>` to create metallic or light/shadow effects.
2. **Grid**: Use `<pattern>` to define precision grid backgrounds with opacity controlled at 0.05-0.1.
3. **Opacity**: Strictly use `fill-opacity` / `stroke-opacity`.
4. **Clipping/Masking**: `mask` is forbidden; `clipPath` is allowed only on `<image>` under `shared-standards.md` §1.2.

### Forbidden Elements (Blacklist)

- `mask` (masking); `clipPath` is allowed only on `<image>` under `shared-standards.md` §1.2
- `<style>`, `class` (stylesheets; `id` within `<defs>` is allowed)
- `foreignObject` (foreign objects)
- `textPath` (text on path)
- `animate`, `animateTransform`, `set` (animations)

- `rgba()` color format (must use hex + opacity)
- `<g opacity="...">` (group opacity — set individually on each element)

## XI. Placeholder Specification

| Placeholder        | Description           |
| ------------------ | --------------------- |
| `{{TITLE}}`        | Presentation main title |
| `{{SUBTITLE}}`     | Subtitle              |

## XII. Usage Notes (Recommended)

1. **Logo**: Recommend using white PNG Logo to suit dark backgrounds.
2. **Background Images**: Cover background grid is embedded in SVG; no external images needed.
3. **Fonts**: Prefer PowerPoint-safe sans-serif fonts; use Arial for English text unless a custom font is explicitly installed or embedded.
