## X. SVG Technical Constraints

### Mandatory Rules

1. viewBox: `0 0 1280 720`
2. Use `<rect>` elements for backgrounds
3. Text wrapping via `<tspan>` (no `<foreignObject>`)
4. Opacity via `fill-opacity` / `stroke-opacity`, no `rgba()`
5. Forbidden: `mask`, `<style>`, `class`, `foreignObject`. `clipPath` is allowed only on `<image>` under `shared-standards.md` §1.2
6. Forbidden: `textPath`, `animate*`, `script`
7. `marker-start` / `marker-end` conditionally allowed (marker in `<defs>`, `orient="auto"`, shape = triangle/diamond/oval) — see shared-standards.md §1.1

### PPT Compatibility Rules

- No `<g opacity="...">` (group opacity) — set opacity on each child element individually
- Use overlay layers for image transparency
- Inline styles only — no external CSS or `@font-face`

## XI. Placeholder Specification

Templates use `{{PLACEHOLDER}}` format. Common placeholders:

| Placeholder          | Description        |
| -------------------- | ------------------ |

## XII. Usage Notes (Recommended)

1. **Template Deployment**: Copy the template to your project directory.
2. **Asset Replacement**: Replace `大型 logo.png` (592×238) and `右上角 logo.png` (113×50) in the `images` directory.
3. **Content Generation**: Select appropriate page templates based on content needs, and replace content using `{{}}` placeholders.
4. **SVG Generation**: Generate final SVG files via automation scripts.
