Page Types ### 1. Cover Page (01_cover.svg) - **Visual Focus**: Large whitespace or image on the left, dark tech-styled cutout on the right/bottom. - **Decoration**: Dynamic geometric lines (Tech Lines), simulating light beam effects. - **Content Layout**: Title left-aligned or centered floating card style for enhanced hierarchy. ### 2. Table of Contents (02_toc.svg) - **Layout**: Card-style list. Each chapter as a horizontal card with simulated subtle shadow. - **Numbers**: Extra-large semi-transparent numbers in the background (01, 02...) for added design appeal. ### 3.

Layout Patterns (Recommended) ### 1. Card List - Wide cards arranged vertically, suitable for table of contents or key points. - Use shadow simulation (e.g., semi-transparent black rectangles) for a floating effect. ### 2. Contrast Layout - Left-right split: left dark / right light, or left image / right text, emphasizing contrast. ### 3. Radial Layout - Core concept centered with surrounding explanations, suitable for chapter or summary pages. --- ## IX. Spacing Guidelines | Property | Value | Description | | -------------- | ----- | ------------------------ | | **Base Unit** | 8px | 8px grid system | | **Module Gap** | 32px | Comfortable reading gap | | **Card Gap** | 16px | Compact with cohesion | --- ## X. SVG Technical Constraints ### Mandatory Rules 1. **Gradient Support**: Use `` and `` defined within ``. 2. **Shadow Handling**: Use restrained shadows only when an element genuinely floats above another layer. Prefer filter soft shadows from `shared-standards.md` §6; use stacked semi-transparent rectangles only when maximum compatibility is required. 3. **Opacity**: Strictly use `fill-opacity` / `stroke-opacity`. 4. **Clipping/Masking**: `mask` is forbidden; `clipPath` is allowed only on `` under `shared-standards.md` §1.2. --- ## XI. Placeholder Specification | Placeholder | Description | | ------------------ | --------------------- | | `{{TITLE}}` | Presentation main title | | `{{SUBTITLE}}` | Subtitle | | `{{AUTHOR}}` | Presenter / Department | | `{{DATE}}` | Date | | `{{PAGE_TITLE}}` | Content page title | | `{{CHAPTER_NUM}}` | Chapter number (01, 02) | | `{{TOC_ITEM_N_TITLE}}` | TOC item title | | `{{TOC_ITEM_N_DESC}}` | TOC item description | | `{{THANK_YOU}}` | Thank-you message | | `{{CONTACT_INFO}}` | Contact information | | `{{LOGO_LARGE}}` | Cover/back page large Logo | | `{{LOGO_HEADER}}` | Navigation bar small Logo | --- ## XII. Usage Notes (Recommended) 1. **Shadow Handling**: Keep shadows subtle and sparse. Use shared-standards §6 as the authority; vector-rectangle shadows are the compatibility fallback. 2. **Gradients**: To modify gradient colors, adjust `stop-color` values in the `` section. 3. **Logo**: Recommend using transparent PNG. Use inverted (white) Logo for dark background pages.
