feat: v5 style overhaul (#2469)
Style updates:

- New "core" theme serves as base for all other themes (official and third-party)
- New CSS custom properties for simplified customization of "core" theme
  **Note:** List of available properties will be made available in documentation by embedding soruce CSS in docs after merge. Merge is required because embedded CSS needs to be in `main` branch. For now, see `_vars.css` and `_vars-advanced.css` for details.
- New theme "add-ons" modify core theme properties and/or add custom declarations as needed.
- New Prism.js theme support
- New configurable sidebar toggle design
- New typography defaults to system sans-serif and monospace fonts instead of relying on external web font.
- New "Core Dark" theme addon provide dark theme styles. Can optionally be applied based on operating system's light/dark setting using `@media` attribute on `<link>` element.
- New "Vue" theme addon. Closely replicated popular v4 theme while allowing for v5 enhancements.
- New CSS class names available for adding loading indicators, adding sidebar expand/collapse icons, adding sidebar group styles, clamping sidebar links to a single line with ellipses, and changing the sidebar toggle icon.
- New auto-generated gradient background for cover page (ensure gradient hue is > 50 degree apart, use OKLCH color if supported, randomize grandient angle, reduce brightness in dark mode)
- New button styles (basic, primary, secondary)
- New form element styles (text input, radio, checkbox, )
- New "callouts" (previously "important" and "tip" helpers)
- New default syntax highlighting theme (from [docsify-themeable](https://jhildenbiddle.github.io/docsify-themeable/))

- New auto-generated monochromatic color palette
- New form element styles (fields, legend, text input, text area, checkbox, radio, toggles, and select)
- New "headerless" tables
- New `kbd` styles
- New task list style
- New merged navbar styles (consistent with sidebar nav styles)
- New search plugin styles and keyboard shortcut indicators
- Add ability restore previously focused content element after hiding sidebar
- Add "focus trap" when sidebar is visible on mobile (accessibility)
- Add ability for sidebar links to wrap by default (previous single-line w/ ellipsis display available as CSS class on `<body>` option)
- Add sidebar `page-link`, `group`, and `group-title` CSS classes to sidebar markup.
- Add reduced motion media query to set all animation/transition timings to zero
- Update Google Font imports (use new variable vs older fixed width fonts)
- Update primary/secondary button order on coverpage (primary should be first)
- Fix missing merged navbar when loading at desktop resolution then resizing to mobile
- Fix inverted open/close sidebar visibility state at desktop/mobile resolutions
- Fix overflow setting to prevent clipping of element focus ring
- Fix safe area inset margins on mobile in landscape orientation
- Fix inverted "tip" and "warn" class names
- Fix scroll padding to prevent headers from touching top edge of viewport when scrolled to

# Cover
Activate the cover feature by setting `coverpage` to **true**. See [coverpage configuration](configuration.md#coverpage).
## Basic usage
Set `coverpage` to **true**, and create a `_coverpage.md`:
```js
window.$docsify = {
coverpage: true,
};
```
```markdown
<!-- _coverpage.md -->
![logo](_media/icon.svg)
# docsify
> A magical documentation site generator
- Simple and lightweight
- No statically built HTML files
- Multiple themes
[GitHub](https://github.com/docsifyjs/docsify/)
[Get Started](#docsify)
```
## Customization
The cover page can be customized using [theme properties](themes#theme-properties):
<!-- prettier-ignore -->
```css
:root {
--cover-bg : url('path/to/image.png');
--cover-bg-overlay : rgba(0, 0, 0, 0.5);
--cover-color : #fff;
--cover-title-color: var(--theme-color);
--cover-title-font : 600 var(--font-size-xxxl) var(--font-family);
}
```
Alternatively, a background color or image can be specified in the cover page markdown.
```markdown
<!-- background color -->
![color](#f0f0f0)
```
```markdown
<!-- background image -->
![](_media/bg.png)
```
## Coverpage as homepage
Normally, the coverpage and the homepage appear at the same time. Of course, you can also separate the coverpage by [`onlyCover`](configuration.md#onlycover) option.
## Multiple covers
If your docs site is in more than one language, it may be useful to set multiple covers.
For example, your docs structure is like this
```text
.
└── docs
├── README.md
├── guide.md
├── _coverpage.md
└── zh-cn
├── README.md
└── guide.md
└── _coverpage.md
```
Now, you can set
```js
window.$docsify = {
coverpage: ['/', '/zh-cn/'],
};
```
Or a special file name
```js
window.$docsify = {
coverpage: {
'/': 'cover.md',
'/zh-cn/': 'cover.md',
},
};
```
