prep for v0.4.0.rc3

* Optimize simple navigation cases

Fix inefficiency reported in feedback on v0.4.0.rc2 (see discussion #958).

This PR:

* essentially reverts `_includes/nav.html` to v0.4.0.rc1
* preserves the ARIA labels added by #950
* adds a test to optimize builds of sites that rely on `title` fields to order pages.

Building the `endoflife.date` site (130 pages) now takes only about 7 seconds.

Building the `machinetranslate.org` site ( 350 pages) takes about 7 minutes. (Without the added test, it takes just over 5 minutes: the condition of the test is merely to compare the size of two arrays, but that is apparently enough to prevent Jekyll from applying some optimization).

A warning is added to the docs about the need for numbers to be in quotes when used as title values.

* Update navigation-structure.md

A clarification is added to the docs about the need for numbers to be in quotes when used as title values.

* Simplify the control and data flow

- Defer concatenation of `string_order_pages` with `title_order_pages` until needed.
- Replace tests on size with tests for `empty`.
- Rename variables accordingly.

* Fix child nav order

This PR started from the navigation in RC1. Some cosmetic improvements had been made in RC2. This commit adds some of those changes to this PR.

It also fixes a bug (revealed by a new regression test) due to a reference to `node.child_nav_order` instead of `child.child_nav_order`, which prevented reversal of the order in children of children. Presumably a top-level reversal should apply only to direct children, and not to grandchildren. The latter interpretation would be very confusing in a deep multi-level hierarchy.

* Allow pages with numeric titles

An omitted `nav_order` value should default to the `title` value, regardless of its type. Jekyll 3 gives build errors when numbers and strings are sorted together. This commit drops the assumption that `title` values are always strings – a 404 page naturally has a numeric title. It updates the docs page accordingly.

The extra code does not affect the build time for the `endoflife.date` site (7 seconds). For the `machinetranslate` site, changing the title of the 404 page to a number increases the build time from 7 minutes to 9 minutes – the `nav_order` numbers on that site are program-generated in the range 1..1000, which might be atypical.

This commit has not yet been checked using the regression tests.

The gemspec used for testing specifies `spec.add_runtime_dependency "jekyll", "~> 3.8.5"`, and `Gemfile.lock` shows `jekyll (3.8.7)`.

* Update nav.html

Add comment about an optimization that will be possible in Jekyll 4.

* Update nav.html

- Update the comment about optimization possibility.
- TEMPORARILY add Jekyll 3 code for conditionally optimizing.

* Update nav.html

Minor improvements and cosmetic changes.

* Major revision

This update is based on extensive experimentation and profiling with alternative versions of the Liquid code used to build the main navigation panel.

Due to the fragility of Jekyll's optimizations, combining alternative approaches with conditionals turned out to be too expensive: merely adding a condition to check whether some array of pages is empty can add about 20% to the build time!

The current code avoids sorting pages on `nav_order` and `title` fields together. The standard way of doing that in Jekyll is to use the `group_by` filter; but extracting the sorted pages from the groups turned out to be too inefficient (as seen in RC1), as was generating links directly from the groups (in RC2).

Making all pages with `nav_order` values come before all those ordered by their `title` values is not ideal (it doesn't support tweaking the relative order of two pages in a list of pages ordered by their titles) but it appears to be necessary for efficient builds on large sites.

This version has not yet been fully tested for regression, but otherwise seems to give the expected navigation on the endoflife.date and machinetranslate websites. (I'm unable to install the Python-based how2data repository on my laptop, due to package version issues on Apple silicon).

+## HEAD
+
+{: .note }
+This website is built from the `HEAD` of the `main` branch of the theme repository.
+
+{: .warning }
+This website includes docs for some new features that are not available in `v0.4.0.rc2` and `v0.3.3`!
+
+Changes to `main` that are *not* in the latest pre-release:

+
+## Pre-release v0.4.0.rc3
+
+Hi there! This is (actually) hopefully the last prerelease before `v0.4.0`; in particular, if we find that this prerelease is stable, we'll re-release it as `v0.4.0`.
+
+In general, this is a more mature pre-release; there are few new features. However, we'll highlight [@pdmosses]'s work in [#992] to better optimize nav generation for large sites (ex 100+ pages). We don't expect this to affect most users; however, **it is technically a breaking change**, and we suggest testing your site before upgrading to this prerelease.
+
+We want your feedback! Please [open an issue](https://github.com/just-the-docs/just-the-docs/issues) or [start a discussion](https://github.com/just-the-docs/just-the-docs/discussions) and let us know!
+
+As soon as we get stable test results from major downstream users, we'll push out a `v0.4.0` ASAP - closing out almost 2 years of backlogged work!
+
+### Trying out pre-release `v0.4.0.rc3`
+
+Simlar to the prior release, `v0.4.0.rc3` is a **release candidate** for the theme (i.e., a pre-release) with release `v0.4.0` coming soon. We want your help in testing the changes! As of now, the gem on RubyGems and the repository are updated to `v0.4.0.rc3`.
+
+To use this RC explicitly as a remote theme:
+
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.4.0.rc3
+```
+
+To use this RC explicitly as a gem-based theme, pin the version in your `Gemfile` and re-run `bundle install` or `bundle update just-the-docs`:
+
+```Ruby
+gem "just-the-docs", "0.4.0.rc3"
+```
+
+By default, **users will not be upgraded to `0.4.0.rc3`**. To enforce that explicitly, either:
+
+1. pin your gem version in your `Gemfile`, like so
+```Ruby
+gem "just-the-docs", "0.3.3"
+```
+2. freeze the `remote_theme`, like so
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.3.3
+```

+{: .warning }
+This website includes docs for some new features that are not available in `v0.4.0.rc1` and `v0.3.3`!
+
+Hey there! This is likely the last pre-release before releasing `v0.4.0`, which we plan on doing soon (i.e. before the end of the month) - very exciting! Some new additions to highlight:
+
+- significant improvement on build time of navigation panel by [@pdmosses]
+  - this is big: for a community member with over 300 pages, we shortened the build time from 3 minutes to 30 seconds!
+- improved accessibility features led by [@JPrevost]
+- more docs!
+
+The intention of this release candidate is to gather even more feedback on a potential `v0.4.0`. As it stands, we have not encountered any breaking changes with early adopters of `v0.4.0.rc1`. If you encounter any - for either of our pre-releases - please let us know!
+
+### Trying out pre-release `v0.4.0.rc2`
+
+Simlar to the prior release, `v0.4.0.rc2` is a **release candidate** for the theme (i.e., a pre-release) with release `v0.4.0` coming soon. We want your help in testing the changes! As of now, the gem on RubyGems and the repository are updated to `v0.4.0.rc2`.
+
+To use this RC explicitly as a remote theme:
+
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.4.0.rc2
+```
+
+To use this RC explicitly as a gem-based theme, pin the version in your `Gemfile` and re-run `bundle install` or `bundle update just-the-docs`:
+
+```Ruby
+gem "just-the-docs", "0.4.0.rc2"
+```
+
+By default, **users will not be upgraded to `0.4.0.rc2`**. To enforce that explicitly, either:
+
+1. pin your gem version in your `Gemfile`, like so
+```Ruby
+gem "just-the-docs", "0.3.3"
+```
+2. freeze the `remote_theme`, like so
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.3.3
+```
+

+## Pre-release v0.4.0.rc1
+
+### We're back!
+
+Hi all! The Just the Docs team is excited to have our first pre-release in over two years! It is jam-packed with features and bugfixes that have been requested by the community since 2020. They include:
+
+- The new callouts component
+- Allowing pages and collections to coexist on the navigation pane
+- New styling: dark syntax highlighting, support for jekyll-asciidoc, word-wrapping instead of overflow for various elements
+- More customization: external nav links, custom nav footers, favicon includes, search color and placeholder configuration, mermaid.js support, and nav sorting
+- Over 20 bugfixes! Big ones include fixing the `rake` command, using `relative_url`, and search input color
+- More documentation, especially on using custom includes
+- Updating core dependencies to stable Ruby versions
+- A WIP [template repository](https://github.com/just-the-docs/just-the-docs-template) that allows you to setup your own repository using Just the Docs and GitHub Pages with one click - give it a shot! More documentation, etc. is on the way!
+
+We want your feedback! Are these changes helpful? Are our docs easy to understand? Should new features like `mermaid` be opt-in or opt-out? Please [open an issue](https://github.com/just-the-docs/just-the-docs/issues) or [start a discussion](https://github.com/just-the-docs/just-the-docs/discussions) and let us know!
+
+### Trying out pre-release `v0.4.0.rc1`
+
+Due to the massive scope of these changes, we're making `v0.4.0.rc1` avaialble as a **release candidate** for the theme (i.e., a pre-release) with release `v0.4.0` coming soon. We want your help in testing the changes! As of now, the gem on RubyGems and the repository are updated to `v0.4.0.rc1`.
+
+To use this RC explicitly as a remote theme:
+
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.4.0.rc1
+```
+
+To use this RC explicitly as a gem-based theme, pin the version in your `Gemfile` and re-run `bundle install` or `bundle update just-the-docs`:
+
+```Ruby
+gem "just-the-docs", "0.4.0.rc1"
+```
+
+### Staying on `v0.3.3`
+
+If you're not ready to make the switch, that's alright! If your version of just-the-docs is pinned to `v0.3.3` (i.e. by a `Gemfile.lock` or in `remote_theme`, then there's nothing you need to do.
+
+If you have not pinned your theme version, you should either:
+
+1. pin your gem version in your `Gemfile`, like so
+```Ruby
+gem "just-the-docs", "0.3.3"
+```
+2. freeze the `remote_theme`, like so
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.3.3
+```
+
+{: .warning }
+Use of branches for closed PRs (e.g., [#466], [#578]) is now deprecated, as those branches have been (directly or indirectly) merged, and they may be deleted after the pre-release of `v0.4.0.rc1`.
+
+### Maintenance
+
+Internally, our maintainer team has expanded: [Patrick Marsceill][@pmarsceill], the original maintainer, has stepped down from an active role after almost 4 years! We're very thankful for the work that he's done to create and maintain one of the most popular Jekyll themes. Please join us in giving him thanks!
+
+The new core team currently consists of [@mattxwang], [@pdmosses], [@skullface], [@dougaitken], and [@max06]. Over the past six months, we've been triaging and merging in PRs, as well as contributing our own fixes. We'll continue to address open issues, merge in PRs from the community, and plan out the future of Just the Docs. If you'd like to contribute, now is a great time!

+
+### Roadmap
+
+In the short-term, we're committed to tidying up everything for a `v0.4.0` release. This involves fixing bugs reported from the community in this pre-release, as well as continually merging in minor PRs.
+
+We're also scoping out medium and long-term projects, and want to keep you in the loop. These include:
+
+- upgrading to Jekyll 4, and stopping support for Jekyll 3
+- versioned docs - issue [#728]
+- improved accessibility - issues [#566], [#870]
+- internationalization (i18n) - issue [#59]
+- recursive/multi-level navigation - PR [#462]
+- toggleable dark mode - issue [#234]
+
+as well as DX improvements like better regression tests, CI, and tooling. If you're interested in any of these, please join us [on GitHub](https://github.com/just-the-docs/just-the-docs) - any contribution (raising an issue, writing docs, or submitting a PR) is welcome!

@@ -63,6 +73,8 @@ Bug reports and pull requests are welcome on GitHub at https://github.com/pmarsc
 
 To set up your environment to develop this theme, run `bundle install`.
 
+A modern [devcontainer configuration](https://code.visualstudio.com/docs/remote/containers) for VSCode is included.
+
 Your theme is set up just like a normal Jekyll site! To test your theme, run `bundle exec jekyll serve` and open your browser at `http://localhost:4000`. This starts a Jekyll server using your theme. Add pages, documents, data, etc. like normal to test your theme's contents. As you make modifications to your theme and to your content, your site will regenerate and you should see the changes in the browser after a refresh, just like normal.
 
 When the theme is released, only the files in `_layouts`, `_includes`, and `_sass` tracked with Git will be released.

+# OneDarkJekyll
+
+*Use Atom's One Dark syntax colors in your Jekyll powered blog!*
+
+It's LESS file which can be compiled to a - Pygments, Rouge compatible - stylesheet from Atom editor's One Dark syntax theme (and any theme based on it, for example One Dark Vivid, Firewatch, etc.).
+
+Download the stylesheet files or compile a new one from any Atom syntax theme which based on One Dark (the variable names in `colors.less` must match with One Dark's)
+
+## Create a new syntax stylesheet
+
+1. `npm install -g less less-plugin-clean-css`
+2. Clone this repository
+3. Download the `colors.css` file from the syntax theme's repository (for example https://github.com/atom/one-dark-syntax/blob/master/styles/colors.less in case of One-Dark)
+4. Put the previously downloaded file next to `syntax.less`
+5. Run `lessc syntax.less syntax.css --clean-css`
+6. Use the `syntax.css`
+
+It's not final and in case you find any error/improvement feel free to create a PR. :)
+
+----
+
+# UPDATES FOR USE IN JUST-THE-DOCS:
+
+1. Layout added in `*.css`
+2. Renamed `*.css` to `*.scss`

+## Callouts
+
+To use this feature, you need to configure a `color` and (optionally) `title` for each kind of callout you want to use, e.g.:
+
+```yaml
+callouts:
+  warning:
+    title: Warning
+    color: red
+```
+
+This uses the color `$red-000` for the background of the callout, and `$red-300` for the title and box decoration.[^dark] You can then style a paragraph as a `warning` callout like this:
+
+```markdown
+{: .warning }
+A paragraph...
+```
+
+[^dark]:
+    If you use the `dark` color scheme, this callout uses `$red-300` for the background, and `$red-000` for the title.
+
+The colors `grey-lt`, `grey-dk`, `purple`, `blue`, `green`, `yellow`, and `red` are predefined; to use a custom color, you need to define its `000` and `300` levels in your SCSS files. For example, to use `pink`, add the following to your `_sass/custom/custom.scss` file:
+
+```scss
+$pink-000: #f77ef1;
+$pink-100: #f967f1;
+$pink-200: #e94ee1;
+$pink-300: #dd2cd4;
+```
+
+You can override the default `opacity` of the background for a particular callout, e.g.:
+
+```yaml
+callouts:
+  custom:
+    color: pink
+    opacity: 0.3
+```
+
+You can change the default opacity (`0.2`) for all callouts, e.g.:
+
+```yaml
+callouts_opacity: 0.3
+```
+
+You can also adjust the overall level of callouts.
+The value of `callouts_level` is either `quiet` or `loud`;
+`loud` increases the saturation and lightness of the backgrounds.
+The default level is `quiet` when using the `light` or custom color schemes,
+and `loud` when using the `dark color scheme.`
+
+See [Callouts]({{ site.baseurl }}{% link docs/ui-components/callouts.md %}) for more information.

+
+## Override includes
+
+You can customize the theme by overriding any of the custom [Jekyll includes](https://jekyllrb.com/docs/includes/) files that it provides.
+
+To do this, create an `_includes` directory and make a copy of the specific file you wish to modify. The content in this file will override the theme defaults. You can learn more about this process in the Jekyll docs for [Overriding theme defaults](https://jekyllrb.com/docs/themes/#overriding-theme-defaults).
+
+Just the Docs provides the following custom includes files:
+
+### Custom TOC Heading
+
+`_includes/toc_heading_custom.html`
+
+If the page has any child pages, and `has_toc` is not set to `false`, this content appears as a heading above the [auto-generating list of child pages]({{ site.baseurl }}{% link docs/navigation-structure.md %}#auto-generating-table-of-contents) after the page's content.
+
+#### Example
+{: .no_toc }
+
+To change the default TOC heading to "Contents", create `_includes/toc_heading_custom.html` and add:
+```html
+<h2 class="text-delta">Contents</h2>
+```
+
+The (optional) `text-delta` class makes the heading appear as **Contents**{:.text-delta} .
+
+### Custom Footer
+
+`_includes/footer_custom.html`
+
+This content appears at the bottom of every page's main content. More info for this include can be found in the [Configuration - Footer content]({{ site.baseurl }}{% link docs/configuration.md %}#footer-content).
+
+### Custom Head
+
+`_includes/head_custom.html`
+
+Any HTML added to this file will be inserted before the closing `<head>` tag. This might include additional `<meta>`, `<link>`, or `<script>` tags.
+
+#### Example
+{: .no_toc }
+
+To add a custom favicon, create `_includes/head_custom.html` and add:
+```html
+<link rel="shortcut icon" type="image/png" href="{{site.baseurl}}/path/to/your/favicon.png">
+```
+
+### Custom Header
+
+`_includes/header_custom.html`
+
+Content added to this file appears at the top of every page's main content between the site search and auxiliary links if they are enabled. If `search_enabled` were set to false and `aux_links` were removed, the content of `header_custom.html` would occupy the space at the top of every page.
+
+### Custom Nav Footer
+
+`_includes/nav_footer_custom.html`
+
+Any content added to this file will appear at the bottom left of the page below the site's navigation. By default an attribution to Just the Docs is displayed which reads, `This site uses Just the Docs, a documentation theme for Jekyll.`.
+
+### Custom Search Placeholder
+
+`_includes/search_placeholder_custom.html`
+
+Content added to this file will replace the default placeholder text in the search bar (and its `aria-label`), after stripping HTML and leading/trailing whitespace. By default, the content of the include is:
+
+{% raw %}
+
+```liquid
+Search {{site.title}}
+```
+
+{% endraw %}
+
+Override this file to render a custom placeholder. One common use-case is internationalization; for example,
+
+{% raw %}
+
+```liquid
+Chercher notre site
+```
+
+{% endraw %}
+
+would make the placeholder text "Chercher notre site". [Liquid code](https://jekyllrb.com/docs/liquid/) (including [Jekyll variables](https://jekyllrb.com/docs/variables/)) is also supported.

-# Exclusion
-
-Pages excluded from the main navigation can have parents and children. Navigation to and between excluded pages can be supported by the auto-generating list of child pages inserted at the bottom of each page, and by links to parents in the breadcrumbs at the top of each page.
-
-The following tests cover all combinations of excluded and included pages for the top level, child pages, and grandchild pages. The last binary digit in a page title indicates whether the page is included (1) or excluded (0); preceding digits refer to its parent and grandparent.

-This page does not have a `title`, and it is excluded from the navigation -- unless it is located in a Jekyll collection (which provides default titles). To exclude a title-less page from the navigation, regardless of whether it is located in a collection, set `nav_exclude: true`.
