This replaceable note exists to keep the **Math**, **Code**, and **Web Dev** tag pages meaningful during early validation.

## Tiny model

Inline math can express a quick estimate like $n \log n$, while display math can show the full relationship:

$$
T(n) = O(n \log n) + O(k)
$$

## Practical reminder

- Prefer simple explanations before formulas.
- Add runnable code when it clarifies an idea.
- Link back to related posts, such as the [starter showcase](/posts/starter-mdx-showcase/).

```js title="estimate.js" {1,4}
export function estimate(items, constant = 1) {
  const n = Math.max(items.length, 1)
  return n * Math.log2(n) + constant
}
```
