+
+## Design Philosophy
+
+Vesper was designed with these principles in mind:
+
+1. **Content First** - The reader is the primary focus. All UI elements can be hidden.
+2. **Typography Matters** - Reading should be comfortable. We use Inter with carefully tuned line heights (1.7), optimal line width (~65 characters), and generous whitespace.
+3. **Dark by Default** - The deep onyx base color (#282C33) reduces eye strain and looks professional.
+4. **Keyboard Driven** - Power users can do everything with keyboard shortcuts.
+5. **Minimalist Chrome** - The interface gets out of your way.
+
+---
+
+## Color Palette
+
+| Color | Hex | Usage |
+|-------|-----|-------|
+| Base | `#282C33` | Main window background |
+| Surface | `#2D323B` | Elevated elements, cards |
+| Overlay | `#333942` | Dropdowns, modals |
+| Text Primary | `#E4E6EB` | Main content |
+| Text Secondary | `#ABB0B8` | UI labels |
+| Accent | `#6B8AFF` | Links, highlights |

+  // Code block nested
+  const x = 1;
+  ```
+- Item 2
+
+### Task List with Formatting
+
+- [x] **Completed** task with *italic*
+- [ ] *Incomplete* with `code`
+- [x] ==Highlighted== and **bold** and *italic*

+
+## 11. Heading + List Combinations
+
+### Heading followed by formatted list
+
+#### Subheading
+
+- **Bold item**
+- *Italic item*
+- `Code item`
+
+### Multiple headings in sequence
+
+## Section 1
+
+- Item 1
+- Item 2
+
+## Section 2
+
+1. Ordered 1
+2. Ordered 2
+
+### Heading within list (edge case)
+
+- Normal item
+- #### Not a heading (just text)
+- Normal item
+
+---
+
+## 12. Links + Code + Bold + Italic combinations
+
+- **[Bold link](https://example.com)**
+- *[Italic link](https://example.com)*
+- [`Code link`](https://example.com)
+- **[Link](https://example.com)** with `code` and *italic*
+- ***[All combined](https://example.com)*** with `more code`
+
+---
+
+## 13. Tables + Lists combinations
+
+| Table | With | Formatting |
+|-------|------|-----------|
+| - List in table | - Another | - Item |
+| **Bold** | *Italic* | `Code` |
+
+- Table below list:
+
+| Col1 | Col2 |
+|------|------|
+| A    | B    |
+
+- List below table:
+
+  | Col1 | Col2 |
+  |------|------|
+  | C    | D    |
+
+---
+
+## 14. All Elements in One Paragraph
+
+This is a paragraph with **bold**, *italic*, ***bold italic***, `inline code`, [a link](https://example.com), ![an image](https://via.placeholder.com/50x20.png), ~~strikethrough~~, ==highlight==, and ^superscript^, all in one paragraph. It's quite long and should test how your renderer handles multiple formatting elements combined.
+
+---
+
+## 15. Edge Case: Empty Elements
+
+- 
+- Item after empty
+
+>
+> Empty blockquote

+
+## 16. Deep Nesting
+
+1. Level 1
+   - Level 2
+     - Level 3
+       - Level 4
+         - Level 5
+           - Level 6
+             - **Deep bold**
+             - *Deep italic*
+             - `Deep code`
+
+---
+
+## 17. Code Blocks with Language and Formatting
+
+```javascript
+// JavaScript with **fake bold** (just text)
+const greet = (name) => {
+  return `Hello, ${name}!`; // Template literal
+};
+```
+
+```python
+# Python with *italic* comments
+def hello():
+    """Docstring with **bold**"""
+    return "Hello"
+```
+
+```html
+<!-- HTML comment with **bold** -->
+<div class="container">
+  <p>Paragraph with *italic*</p>
+</div>
+```
+
+---
+
+## 18. Final Complex Example
+
+> ### Blockquote Heading
+> 
+> This is a blockquote that contains:
+> 
+> - A **bold** list item
+> - An *italic* list item  
+> - A `code` list item
+> - A [link](https://example.com) item
+> 
+> And then continues with more text that has **bold**, *italic*, and `code` formatting.
+> 
+> It also has a nested list:
+> 
+> 1. First nested **bold** item
+> 2. Second nested *italic* item
+> 3. Third nested `code` item
+
+---
+
+This covers virtually every possible combination of markdown elements!
