chore: Port FreeSewing.dev to docusaurus

The replaces the NextJS site powering FreeSewing.dev with a Docusaurus
setup. It's part of my efforts to simplify FreeSewing's setup so we can
focus on our core value proposition.

+title: embed
+---
+
+The `embed` setting controls whether to generate an SVG document suitable for
+printing, or for embedding on a web page.
+
+## Signature
+
+```js
+const settings = {
+  Boolean embed=false
+}
+```
+
+The default for `embed` is `false` which will include the `width` and `height`
+attributes in the SVG tag, thereby making it suitable for printing.
+
+When set to `true` the `width` and `height` attributes will not be added which
+allows you to inject the SVG into an HTML document, where it will responsively
+scale.
+
+## Example
+
+```js
+import { Aaron } from "@freesewing/aaron"
+
+const pattern = new Aaron({
+  embed: true
+})
+```
