This PR incorporates design tweaks from #2922 without the home page or
content changes.
These are:
- Replacing all `hello@tldraw.com` with `sales@tldraw.com`
- Fix mailto links.
- Showing the first item in a section on direct routes to the section
- Splitting the article page for human-written content from article page
for generated content
- Splitting the layout for the landing page from the rest of the site
(temporarily identical to the regular content)
- Removing headings from left sidebar
- Restoring headings in right sidebar for human-written pages with > 1
heading link
- Styling block quote
- Adjusting section link appearance / layout in header / menu
- Changing the order of search results to preference docs over examples
- Updating copy on events
- Removing copy on user interface menus
- Adding hero as prop to all articles
- Updated icon
- Fixing a few broken links
- Replaces the sandpack code blocks with hljs code blocks, except in
examples.
### Change Type
- [x] `documentation` — Changes to the documentation only[^2]
- add TOC for Reference section
- make external links use _blank to open a new tab
- fix some more /gen links spots I missed, oops
- add a general redirect from old /gen links → /reference
- some more stylistic touchups
### Change Type
- [x] `documentation` — Changes to the documentation only[^2]
### Release Notes
- Docs: further cleanup following restructure.
This PR adds the docs app back into the tldraw monorepo.
## Deploying
We'll want to update our deploy script to update the SOURCE_SHA to the
newest release sha... and then deploy the docs pulling api.json files
from that release. We _could_ update the docs on every push to main, but
we don't have to unless something has changed. Right now there's no
automated deployments from this repo.
## Side effects
To make this one work, I needed to update the lock file. This might be
ok (new year new lock file), and everything builds as expected, though
we may want to spend some time with our scripts to be sure that things
are all good.
I also updated our prettier installation, which decided to add trailing
commas to every generic type. Which is, I suppose, [correct
behavior](https://github.com/prettier/prettier-vscode/issues/955)? But
that caused diffs in every file, which is unfortunate.
### Change Type
- [x] `internal` — Any other changes that don't affect the published
package[^2]
