feat(security,ui): self-host React deps, Tailwind, fonts; strict CSP; local QR; better selection state

Replace CDN React/ReactDOM/Babel with local libs; remove Babel and inline scripts
Build Tailwind locally, add safelist; switch to assets/tailwind.css
Self-host Font Awesome and Inter (CSS + woff2); remove external font CDNs
Implement strict CSP (no unsafe-inline/eval; scripts/styles/fonts from self)
Extract inline handlers; move PWA scripts to external files
Add local QR code generation (qrcode lib) and remove api.qrserver.com
Improve SessionTypeSelector visual selection (highlighted background and ring)
Keep PWA working with service worker and offline assets
Refs: CSP hardening, offline-first, no external dependencies

## API
### ansiRegex(options?)
Returns a regex for matching ANSI escape codes.
#### options
Type: `object`
##### onlyFirst
Type: `boolean`<br>
Default: `false` *(Matches any ANSI escape codes in a string)*
Match only the first ANSI escape.
## FAQ
### Why do you test for codes not in the ECMA 48 standard?
Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
> [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
<img src="screenshot.svg" width="900">
## Install
```
$ npm install ansi-styles
```
## Usage
```js
const style = require('ansi-styles');
console.log(`${style.green.open}Hello world!${style.green.close}`);
// Color conversion between 16/256/truecolor
// NOTE: If conversion goes to 16 colors or 256 colors, the original color
// may be degraded to fit that color palette. This means terminals
// that do not support 16 million colors will best-match the
// original color.
console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
console.log(style.color.ansi16m.hex('#abcdef') + 'Hello world!' + style.color.close);
```
## API
Each style has an `open` and `close` property.
## Styles
### Modifiers
- `reset`
- `bold`
- `dim`
- `italic` *(Not widely supported)*
- `underline`
- `inverse`
- `hidden`
- `strikethrough` *(Not widely supported)*
### Colors
- `black`
- `red`
- `green`
- `yellow`
- `blue`
- `magenta`
- `cyan`
- `white`
- `blackBright` (alias: `gray`, `grey`)
- `redBright`
- `greenBright`
- `yellowBright`
- `blueBright`
- `magentaBright`
- `cyanBright`
- `whiteBright`
### Background colors
- `bgBlack`
- `bgRed`
- `bgGreen`
- `bgYellow`
- `bgBlue`
- `bgMagenta`
- `bgCyan`
- `bgWhite`
- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
- `bgRedBright`
- `bgGreenBright`
- `bgYellowBright`
- `bgBlueBright`
- `bgMagentaBright`
- `bgCyanBright`
- `bgWhiteBright`
## Advanced usage
By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
- `style.modifier`
- `style.color`
- `style.bgColor`
###### Example
```js
console.log(style.color.green.open);
```
Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
###### Example
```js
console.log(style.codes.get(36));
//=> 39
```
## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
The following color spaces from `color-convert` are supported:
- `rgb`
- `hex`
- `keyword`
- `hsl`
- `hsv`
- `hwb`
- `ansi`
- `ansi256`
To use these, call the associated conversion function with the intended output, for example:
```js
style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code

# cliui
[![Build Status](https://travis-ci.org/yargs/cliui.svg)](https://travis-ci.org/yargs/cliui)
[![Coverage Status](https://coveralls.io/repos/yargs/cliui/badge.svg?branch=)](https://coveralls.io/r/yargs/cliui?branch=)
[![NPM version](https://img.shields.io/npm/v/cliui.svg)](https://www.npmjs.com/package/cliui)
[![Standard Version](https://img.shields.io/badge/release-standard%20version-brightgreen.svg)](https://github.com/conventional-changelog/standard-version)
easily create complex multi-column command-line-interfaces.
## Example
```js
var ui = require('cliui')()
ui.div('Usage: $0 [command] [options]')
ui.div({
text: 'Options:',
padding: [2, 0, 2, 0]
})
ui.div(
{
text: "-f, --file",
width: 20,
padding: [0, 4, 0, 4]
},
{
text: "the file to load." +
chalk.green("(if this description is long it wraps).")
,
width: 20
},
{
text: chalk.red("[required]"),
align: 'right'
}
)
console.log(ui.toString())
```
<img width="500" src="screenshot.png">
## Layout DSL
cliui exposes a simple layout DSL:
If you create a single `ui.div`, passing a string rather than an
object:
* `\n`: characters will be interpreted as new rows.
* `\t`: characters will be interpreted as new columns.
* `\s`: characters will be interpreted as padding.
**as an example...**
```js
var ui = require('./')({
width: 60
})
ui.div(
'Usage: node ./bin/foo.js\n' +
' <regex>\t provide a regex\n' +
' <glob>\t provide a glob\t [required]'
)
console.log(ui.toString())
```
**will output:**
```shell
Usage: node ./bin/foo.js
<regex> provide a regex
<glob> provide a glob [required]
```
## Methods
```js
cliui = require('cliui')
```
### cliui({width: integer})
Specify the maximum width of the UI being generated.
If no width is provided, cliui will try to get the current window's width and use it, and if that doesn't work, width will be set to `80`.
### cliui({wrap: boolean})
Enable or disable the wrapping of text in a column.
### cliui.div(column, column, column)
Create a row with any number of columns, a column
can either be a string, or an object with the following
options:
* **text:** some text to place in the column.
* **width:** the width of a column.
* **align:** alignment, `right` or `center`.
* **padding:** `[top, right, bottom, left]`.
* **border:** should a border be placed around the div?
### cliui.span(column, column, column)
Similar to `div`, except the next row will be appended without
a new line being created.
### cliui.resetOutput()
Resets the UI elements of the current cliui instance, maintaining the values
set for `width` and `wrap`.

# color-convert
[![Build Status](https://travis-ci.org/Qix-/color-convert.svg?branch=master)](https://travis-ci.org/Qix-/color-convert)
Color-convert is a color conversion library for JavaScript and node.
It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
```js
var convert = require('color-convert');
convert.rgb.hsl(140, 200, 100); // [96, 48, 59]
convert.keyword.rgb('blue'); // [0, 0, 255]
var rgbChannels = convert.rgb.channels; // 3
var cmykChannels = convert.cmyk.channels; // 4
var ansiChannels = convert.ansi16.channels; // 1
```
# Install
```console
$ npm install color-convert
```
# API
Simply get the property of the _from_ and _to_ conversion that you're looking for.
All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
```js
var convert = require('color-convert');
// Hex to LAB
convert.hex.lab('DEADBF'); // [ 76, 21, -2 ]
convert.hex.lab.raw('DEADBF'); // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
// RGB to CMYK
convert.rgb.cmyk(167, 255, 4); // [ 35, 0, 98, 0 ]
convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
```
### Arrays
All functions that accept multiple arguments also support passing an array.
Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
```js
var convert = require('color-convert');
convert.rgb.hex(123, 45, 67); // '7B2D43'
convert.rgb.hex([123, 45, 67]); // '7B2D43'
```
## Routing
Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).

# emoji-regex [![Build status](https://travis-ci.org/mathiasbynens/emoji-regex.svg?branch=master)](https://travis-ci.org/mathiasbynens/emoji-regex)
_emoji-regex_ offers a regular expression to match all emoji symbols (including textual representations of emoji) as per the Unicode Standard.
This repository contains a script that generates this regular expression based on [the data from Unicode v12](https://github.com/mathiasbynens/unicode-12.0.0). Because of this, the regular expression can easily be updated whenever new emoji are added to the Unicode standard.
## Installation
Via [npm](https://www.npmjs.com/):
```bash
npm install emoji-regex
```
In [Node.js](https://nodejs.org/):
```js
const emojiRegex = require('emoji-regex');
// Note: because the regular expression has the global flag set, this module
// exports a function that returns the regex rather than exporting the regular
// expression itself, to make it impossible to (accidentally) mutate the
// original regular expression.
const text = `
\u{231A}: ⌚ default emoji presentation character (Emoji_Presentation)
\u{2194}\u{FE0F}: ↔️ default text presentation character rendered as emoji
\u{1F469}: 👩 emoji modifier base (Emoji_Modifier_Base)
\u{1F469}\u{1F3FF}: 👩🏿 emoji modifier base followed by a modifier
`;
const regex = emojiRegex();
let match;
while (match = regex.exec(text)) {
const emoji = match[0];
console.log(`Matched sequence ${ emoji } — code points: ${ [...emoji].length }`);
}
```
Console output:
```
Matched sequence ⌚ — code points: 1
Matched sequence ⌚ — code points: 1
Matched sequence ↔️ — code points: 2
Matched sequence ↔️ — code points: 2
Matched sequence 👩 — code points: 1
Matched sequence 👩 — code points: 1
Matched sequence 👩🏿 — code points: 2
Matched sequence 👩🏿 — code points: 2
```
To match emoji in their textual representation as well (i.e. emoji that are not `Emoji_Presentation` symbols and that arent forced to render as emoji by a variation selector), `require` the other regex:
```js
const emojiRegex = require('emoji-regex/text.js');
```
Additionally, in environments which support ES2015 Unicode escapes, you may `require` ES2015-style versions of the regexes:
```js
const emojiRegex = require('emoji-regex/es2015/index.js');
const emojiRegexText = require('emoji-regex/es2015/text.js');
```

If you are installing with npm, you can try not copying the "node_modules"
directory when you copy the files over, and running "npm ci" or "npm install"
on the destination platform after the copy. Or you could consider using yarn
instead of npm which has built-in support for installing a package on multiple
platforms simultaneously.
If you are installing with yarn, you can try listing both this platform and the
other platform in your ".yarnrc.yml" file using the "supportedArchitectures"

If you are installing with npm, you can try ensuring that both npm and node are
not running under Rosetta 2 and then reinstalling esbuild. This likely involves
changing how you installed npm and/or node. For example, installing node with

## API
### findUp(name, options?)
### findUp(matcher, options?)
Returns a `Promise` for either the path or `undefined` if it couldn't be found.
### findUp([...name], options?)
Returns a `Promise` for either the first path found (by respecting the order of the array) or `undefined` if none could be found.
### findUp.sync(name, options?)
### findUp.sync(matcher, options?)
Returns a path or `undefined` if it couldn't be found.
### findUp.sync([...name], options?)
Returns the first path found (by respecting the order of the array) or `undefined` if none could be found.
#### name
Type: `string`
Name of the file or directory to find.
#### matcher
Type: `Function`
A function that will be called with each directory until it returns a `string` with the path, which stops the search, or the root directory has been reached and nothing was found. Useful if you want to match files with certain patterns, set of permissions, or other advanced use-cases.
When using async mode, the `matcher` may optionally be an async or promise-returning function that returns the path.
#### options
Type: `object`
##### cwd
Type: `string`<br>
Default: `process.cwd()`
Directory to start from.
##### type
Type: `string`<br>
Default: `'file'`<br>
Values: `'file'` `'directory'`
The type of paths that can match.
##### allowSymlinks
Type: `boolean`<br>
Default: `true`
Allow symbolic links to match if they point to the chosen path type.
### findUp.exists(path)
Returns a `Promise<boolean>` of whether the path exists.
### findUp.sync.exists(path)
Returns a `boolean` of whether the path exists.
#### path
Type: `string`
Path to a file or directory.
### findUp.stop
A [`Symbol`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol) that can be returned by a `matcher` function to stop the search and cause `findUp` to immediately return `undefined`. Useful as a performance optimization in case the current working directory is deeply nested in the filesystem.
```js
const path = require('path');
const findUp = require('find-up');
(async () => {
await findUp(directory => {
return path.basename(directory) === 'work' ? findUp.stop : 'logo.png';
});
})();
```

# get-caller-file
[![Build Status](https://travis-ci.org/stefanpenner/get-caller-file.svg?branch=master)](https://travis-ci.org/stefanpenner/get-caller-file)
[![Build status](https://ci.appveyor.com/api/projects/status/ol2q94g1932cy14a/branch/master?svg=true)](https://ci.appveyor.com/project/embercli/get-caller-file/branch/master)
This is a utility, which allows a function to figure out from which file it was invoked. It does so by inspecting v8's stack trace at the time it is invoked.
Inspired by http://stackoverflow.com/questions/13227489
*note: this relies on Node/V8 specific APIs, as such other runtimes may not work*
## Installation
```bash
yarn add get-caller-file
```
## Usage
Given:
```js
// ./foo.js
const getCallerFile = require('get-caller-file');
module.exports = function() {
return getCallerFile(); // figures out who called it
};
```
```js
// index.js
const foo = require('./foo');
foo() // => /full/path/to/this/file/index.js
```
## Options:
* `getCallerFile(position = 2)`: where position is stack frame whos fileName we want.

# p-limit [![Build Status](https://travis-ci.org/sindresorhus/p-limit.svg?branch=master)](https://travis-ci.org/sindresorhus/p-limit)
> Run multiple promise-returning & async functions with limited concurrency
## Install
```
$ npm install p-limit
```
## Usage
```js
const pLimit = require('p-limit');
const limit = pLimit(1);
const input = [
limit(() => fetchSomething('foo')),
limit(() => fetchSomething('bar')),
limit(() => doSomething())
];
(async () => {
// Only one promise is run at once
const result = await Promise.all(input);
console.log(result);
})();
```
## API
### pLimit(concurrency)
Returns a `limit` function.
#### concurrency
Type: `number`\
Minimum: `1`\
Default: `Infinity`
Concurrency limit.
### limit(fn, ...args)
Returns the promise returned by calling `fn(...args)`.
#### fn
Type: `Function`
Promise-returning/async function.
#### args
Any arguments to pass through to `fn`.
Support for passing arguments on to the `fn` is provided in order to be able to avoid creating unnecessary closures. You probably don't need this optimization unless you're pushing a *lot* of functions.
### limit.activeCount
The number of promises that are currently running.
### limit.pendingCount
The number of promises that are waiting to run (i.e. their internal `fn` was not called yet).
### limit.clearQueue()
Discard pending promises that are waiting to run.
This might be useful if you want to teardown the queue at the end of your program's lifecycle or discard any function calls referencing an intermediary state of your app.
Note: This does not cancel promises that are already running.
## FAQ
### How is this different from the [`p-queue`](https://github.com/sindresorhus/p-queue) package?
This package is only about limiting the number of concurrent executions, while `p-queue` is a fully featured queue implementation with lots of different options, introspection, and ability to pause the queue.

# p-locate [![Build Status](https://travis-ci.org/sindresorhus/p-locate.svg?branch=master)](https://travis-ci.org/sindresorhus/p-locate)
> Get the first fulfilled promise that satisfies the provided testing function
Think of it like an async version of [`Array#find`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/find).
## Install
```
$ npm install p-locate
```
## Usage
Here we find the first file that exists on disk, in array order.
```js
const pathExists = require('path-exists');
const pLocate = require('p-locate');
const files = [
'unicorn.png',
'rainbow.png', // Only this one actually exists on disk
'pony.png'
];
(async () => {
const foundPath = await pLocate(files, file => pathExists(file));
console.log(foundPath);
//=> 'rainbow'
})();
```
*The above is just an example. Use [`locate-path`](https://github.com/sindresorhus/locate-path) if you need this.*
## API
### pLocate(input, tester, [options])
Returns a `Promise` that is fulfilled when `tester` resolves to `true` or the iterable is done, or rejects if any of the promises reject. The fulfilled value is the current iterable value or `undefined` if `tester` never resolved to `true`.
#### input
Type: `Iterable<Promise | unknown>`
An iterable of promises/values to test.
#### tester(element)
Type: `Function`
This function will receive resolved values from `input` and is expected to return a `Promise<boolean>` or `boolean`.
#### options
Type: `Object`
##### concurrency
Type: `number`<br>
Default: `Infinity`<br>
Minimum: `1`
Number of concurrently pending promises returned by `tester`.
##### preserveOrder
Type: `boolean`<br>
Default: `true`
Preserve `input` order when searching.
Disable this to improve performance if you don't care about the order.
