# Terminal Portfolio
# Sir Blob's Desktop
An Arch Linux terminal-themed portfolio website with Hyprland-style TUI components, built with SvelteKit, Tailwind CSS, and Three.js.
A portfolio website that recreates my Arch Linux desktop (Hyprland, Quickshell bar, kitty terminals) in the browser. Built with SvelteKit 3, Svelte 5 runes and Tailwind CSS 4.
## Features
## Running
- Hyprland-style TUI - Terminal interface inspired by Textual Python TUI
- Interactive command line - Type commands directly into the terminal to navigate and run actions
- Theme Support - Arch, Catppuccin, Wintry, Rose, and Cerberus themes, each with dark/light variants
- Dark/Light Mode - Toggle between dark and light modes
- Keyboard Navigation - Navigate with arrow keys or vim-style j/k
- Native Blog - Markdown posts with tags, authors, syntax highlighting, search, pagination, and an RSS feed
- 3D Model Viewer - Interactive Three.js viewer for .glb models
- QR Links Page - Generate a scannable QR code for any of your links
- Configurable Speed - Per-page typing animation speed
- Responsive - Works on desktop and mobile
- Rich Text Formatting - Colors, backgrounds, text decorations, and sizeable inline icons
## Pages
- Home (`/`) - Neofetch-style intro with navigation
- About (`/about`) - Background and details
- Portfolio (`/portfolio`) - Profile, experience, skills, and contact info
- Projects (`/projects`) - Hub linking out to the three project categories below
- Open Source (`/projects/opensource`) - Projects built and maintained in the open
- Packages (`/projects/packages`) - Published packages and CLI tools
- Hackathons (`/projects/hackathons`) - Hackathon projects, awards, and stats
- Blog (`/blog`) - Native markdown blog with tags, search, pagination, and an RSS feed at `/blog/rss.xml`
- Models (`/models`) - 3D model gallery with interactive viewer
- Components (`/components`) - Showcase of all TUI components
- Links (`/links`) - All links with on-demand QR codes
The navbar exposes Home, About, Projects, and Blog. Portfolio, Models, Components, and Links are reachable directly by URL or with the terminal `cd` command (for example, `cd links`).
## Terminal Commands
Every terminal page has an interactive command line at the bottom. Click the terminal (or just start typing once focused), enter a command, and press Enter. Output is printed back into the terminal.
Use the Up/Down arrows to cycle through command history.
| Command | Aliases | Description |
|---------|---------|-------------|
| `help` | `h`, `?` | List all available commands |
| `clear` | `cls` | Clear the terminal |
| `whoami` | | Show a short bio |
| `neofetch` | `banner` | Display system info with profile picture |
| `skills` | | List skills by category |
| `contact` | `socials` | Show social links as buttons |
| `email` | | Show contact email |
| `cd <page>` | `goto`, `open` | Navigate to a page, including subpages (e.g. `cd projects/opensource`) |
| `ls` | `dir` | List the pages you can visit as a tree, with project subpages nested under `projects/` |
| `theme [name]` | | List or set the color theme |
| `mode [dark\|light]` | | Toggle or set dark/light mode |
| `echo <text>` | | Print text back |
| `cowsay <text>` | | Make a cow say something |
| `date` | | Show the current date and time (Eastern) |
Command definitions live in `src/lib/components/tui/terminal-commands.ts`. Add a new entry to the `commands` list to extend the command set. Pages and their subpages are declared once in the `pageTree` structure in that file, which both `ls` (tree rendering) and `cd` (nested path resolution) read from.
## Configuration
The site configuration is modular - split into focused files in `src/lib/config/` for easier maintenance. You can still import everything from `$lib/config` for backward compatibility.
### Config File Structure
```
src/lib/config/
├── index.ts # Barrel export (re-exports all modules)
├── user.ts # User profile, socials, links, skills
├── layout.ts # Layout dimensions, breakpoints, fonts, navbar, scrollbar
├── theme.ts # Colors, animations, effects, loading screen
├── content.ts # Projects, 3D models, experience, hackathon cards
├── terminal.ts # Terminal settings, TUI styling, speed presets, shortcuts
├── navigation.ts # Navigation links, site metadata, page meta
└── blog.ts # Blog name and tagline shown on /blog
```bash
bun install
bun run dev
bun run build
bun run check
```
### Import Examples
## How the desktop works
```typescript
// Barrel import (backward compatible)
import { user, colorPalette, projects } from '$lib/config';
- The top bar mirrors the blob-shell Quickshell bar: chai menu (app launcher), workspaces 1-9, clock, Discord status and theme picker.
- Every page (`/about`, `/projects/hackathons`, ...) opens as a tiled window, so old resume links still work.
- Terminals open next to it and tile with the Hyprland dwindle layout.
- Desktop icons open a page, a terminal running a command, or an external link.
- On small screens the focused window goes fullscreen and open windows are listed as tabs.
// Direct imports (smaller bundles, faster builds)
import { user, skills, links } from '$lib/config/user';
import { colorPalette, animations } from '$lib/config/theme';
import { openSourceProjects, cards, experience } from '$lib/config/content';
import { terminalSettings, keyboardShortcuts } from '$lib/config/terminal';
import { navigation, site, pageMeta } from '$lib/config/navigation';
```
### Keybinds
### Config Modules
| Keys | Action |
| --- | --- |
| Alt + Enter | Open a kitty terminal |
| Alt + Space | App launcher |
| Alt + Q | Close focused window |
| Alt + F | Fullscreen the page window |
| Alt + J / K | Focus next / previous window |
| Alt + 1-9 | Switch workspace |
| Alt + T | Next theme |
Alt stands in for Super, which browsers do not receive.
## Editing content
Everything you would normally change lives in `content/`. No code changes needed.
| File | Contents |
|------|----------|
| `user.ts` | `user`, `skills`, `links` |
| `layout.ts` | `layout`, `breakpoints`, `fonts`, `navbar`, `scrollbar` |
| `theme.ts` | `colorPalette`, `terminalButtons`, `loadingScreen`, `effects`, `animations` |
| `content.ts` | `openSourceProjects`, `packageProjects`, `models`, `experience`, `cards`, `sortedCards` + types |
| `terminal.ts` | `terminalSettings`, `tuiStyle`, `tuiText`, `pageSpeedSettings`, `pageAutoscrollSettings`, `speedPresets`, `modelViewer`, `particles`, `keyboardShortcuts` |
| `navigation.ts` | `navigation`, `site`, `pageMeta` |
| `blog.ts` | `blogName`, `blogTagline` |
| --- | --- |
| `content/profile.json` | name (shown only on the portfolio page), bio, avatar, education, socials (also used by the links page), skills, interests |
| `content/experience.json` | experience with highlights, tech, awards and links |
| `content/leadership.json` | leadership roles |
| `content/about.json` | hobbies, games, shows, movies |
| `content/projects/opensource.json` | open source projects |
| `content/projects/packages.json` | published packages |
| `content/projects/hackathons.json` | hackathon projects, events and awards |
| `content/projects/research.json` | research roles and projects |
| `content/models.json` | 3D models (files go in `static/models/`) |
| `content/desktop.json` | default theme, workspaces, desktop icons, startup command |
| `content/blog.json` | blog name, tagline, posts per page |
| `content/blog/*.md` | blog posts |
### Example: Key config snippets
### Projects
```typescript
// Toggle theme keys and other shortcuts
export const keyboardShortcuts = {
skip: ['y', 'Y'], // Skip typing animation
toggleTheme: ['t', 'T'], // Toggle dark/light mode
navigateUp: ['ArrowUp', 'k'],
navigateDown: ['ArrowDown', 'j'],
select: ['Enter'],
};
Every project in every category uses the same shape. Only `name`, `description`, `tags` and `links` are required.
// Terminal / typing
export const terminalSettings = {
baseTypeSpeed: 20,
minTypeSpeed: 5,
maxTypeSpeed: 50,
startDelay: 300,
lineDelay: 100,
showCursor: true,
promptStyle: 'full',
scrollMargin: 80,
};
// Color palette (Catppuccin Mocha by default)
export const colorPalette = {
red: '#f38ba8',
green: '#a6e3a1',
yellow: '#f9e2af',
blue: '#89b4fa',
magenta: '#cba6f7',
cyan: '#94e2d5',
white: '#cdd6f4',
gray: '#6c7086',
error: '#f38ba8',
success: '#a6e3a1',
};
```json
{
"name": "HushMap",
"description": "What it does.",
"image": "/hacks/hushmap.png",
"tags": ["Svelte", "FastAPI"],
"featured": true,
"event": { "name": "Bitcamp 2026", "university": "University of Maryland", "location": "College Park, MD", "year": "2026" },
"awards": [{ "track": "Best UI/UX Hack", "place": "Winner" }],
"demoMayBeOffline": false,
"version": "2.2.0",
"links": { "demo": "https://...", "code": "https://...", "devpost": "https://...", "package": "https://...", "article": "https://..." }
}
```
### How to Customize
Featured projects are listed first.
- Edit `config/user.ts` to update your profile, socials, links, and skills
- Edit `config/content.ts` to add projects, models, experience, or hackathon entries
- Edit `config/theme.ts` to change colors, animations, or loading screen
- Edit `config/terminal.ts` to adjust typing speed, TUI styling, or shortcuts
- Edit `config/layout.ts` to change dimensions, breakpoints, or navbar settings
- Edit `config/navigation.ts` to add/remove nav links or update page metadata
### Desktop icons
Changes take effect on next reload. Some values (fonts, CSS variables) may also require adjusting CSS or Tailwind config.
Each icon in `content/desktop.json` has a `label`, an Iconify `icon` and one `open` action:
### Where to Look for Types & Utilities
- `src/lib/config/` - All configuration modules
- `src/lib/components/tui/types.ts` - TerminalLine types
- `src/lib/components/tui/utils.ts` - Parsing utilities and style helpers
- `src/lib/components/tui/terminal-commands.ts` - Interactive command definitions
- `src/lib/stores/theme.ts` - Theme store & `toggleMode()`
- `src/lib/index.ts` - Helper functions (barrel export)
## Links Page
The `/links` page lists everything in the `links` array (a dedicated list, separate from `user.socials`) and renders a scannable QR code for whichever link is selected, plus a clickable button to open it.
Add or remove entries in `src/lib/config/user.ts`:
```typescript
export const links: LinkItem[] = [
{ name: 'GitHub', icon: 'mdi:github', link: 'https://github.com/SirBlobby' },
{ name: 'Email', icon: 'mdi:email', link: `mailto:${user.email}` },
// Add page-only links here without touching user.socials
];
```json
{ "label": "about", "icon": "mdi:account", "open": { "page": "/about" } }
{ "label": "skills.sh", "icon": "mdi:script-text", "open": { "terminal": "skills" } }
{ "label": "github", "icon": "mdi:github", "open": { "url": "https://github.com/SirBlobby" } }
```
QR codes are generated with the `svelte-qrcode` package, loaded on the client.
`{ "terminal": "" }` opens an empty terminal.
## Blog
### Blog posts
The `/blog` page is a native markdown blog — no external blogging platform required.
### Writing a Post
Add a markdown file to the `blogs/` directory at the project root:
Add a markdown file to `content/blog/`. The file name is the URL slug.
```markdown
---
title: My Post Title
author: Your Name
author: Sir Blob
date: 2026-01-01
tags: meta, notes
excerpt: A one line summary shown on the blog list and in the RSS feed.
excerpt: One line summary for the list and the RSS feed.
---
Post content goes here, written in markdown.
Post content in markdown.
```
Posts are picked up automatically via `import.meta.glob` in `src/lib/blog/posts.ts` — no manual registration needed. `author` and `date` are optional; `author` falls back to `user.displayname`.
The RSS feed is at `/blog/rss.xml`.
### Rendering
## Themes
`src/lib/blog/markdown.ts` is a small hand-written markdown-to-HTML renderer (headings, bold/italic, links, images, lists, blockquotes, and fenced code blocks) — no external markdown dependency. Fenced code blocks with a language tag (` ```js `, ` ```python `, etc.) get lightweight syntax highlighting via `src/lib/blog/highlight.ts`, and every code block gets a copy-to-clipboard button.
Themes live in `src/lib/theme/themes.ts` and use the same keys as a blomarchy `colors.toml`, so a theme can be copied over from the dotfiles. Each theme can set a `wallpaper` (from `static/wallpapers/`) and an `activeBorder` gradient. The default theme is set in `content/desktop.json`.
Dates are parsed and formatted in Eastern time via `src/lib/blog/date.ts`, anchored at noon UTC to avoid off-by-one day shifts from timezone conversion.
Shipped themes: Flats (default), Retro 82, Tokyo Night, Catppuccin, Arch Linux, Gruvbox, Nord, Kanagawa, Wintry, Rose, Cerberus, Catppuccin Latte, Rose Pine Dawn.
### Features
## Terminal commands
- Tags with click-to-filter on the blog list
- Full-text search across title, excerpt, and tags
- Pagination (5 posts per page)
- Previous/next post navigation on each post page
- RSS feed at `/blog/rss.xml` (`src/routes/blog/rss.xml/+server.ts`)
`help`, `whoami`, `fastfetch`, `skills`, `contact`, `email`, `experience`, `projects [category]`, `ls`, `cd <page>`, `theme [name]`, `echo`, `cowsay`, `date`, `clear`, `exit`. Page names (`about`, `hackathons`, ...) and social names (`github`, `linkedin`, ...) also work as commands. Tab completes commands, pages after `cd`, themes after `theme` and categories after `projects`; when several match it lists them like bash. Up/Down walk history, Ctrl+L clears.
## Speed Presets
Commands live in `src/lib/terminal/commands/`.
| Preset | Effect |
|--------|--------|
| `instant` | No animation, appears immediately |
| `fast` | 3x faster than normal |
| `normal` | Default typing speed |
| `slow` | 2x slower than normal |
| `typewriter` | 3x slower, classic feel |
## Code layout
## Text Formatting
| Path | Contents |
| --- | --- |
| `src/lib/content/` | typed loader for `content/` |
| `src/lib/blog/` | markdown renderer, frontmatter, highlighting, dates |
| `src/lib/theme/` | theme palettes, stylesheet generation, current theme state |
| `src/lib/desktop/` | window manager, dwindle tiling, keybinds, desktop actions |
| `src/lib/terminal/` | terminal output model and commands |
| `src/lib/site/pages.ts` | page list used by the terminal and launcher |
| `src/lib/components/shell/` | bar, workspaces, clock, theme menu, Discord status |
| `src/lib/server/discord.ts` | Discord bot and presence lookup |
| `src/lib/components/desktop/` | desktop, windows, icons, launcher |
| `src/lib/components/terminal/` | kitty terminal |
| `src/lib/components/ui/` | shared page pieces |
| `src/routes/` | pages |
Use inline formatting with the `(&specs)text(&)` syntax:
## Discord status
### Colors
The bar shows live Discord presence (status, avatar, guild tag, activities). A discord.js bot starts with the server (`src/hooks.server.ts`) and the bar polls `/api/discord` every 30 seconds. Copy `.env.example` to `.env` and fill in:
```typescript
// Basic colors
'(&red)Red text(&)'
'(&green)Green text(&)'
'(&blue)Blue text(&)'
'(&yellow)Yellow text(&)'
'(&magenta)Magenta text(&)'
'(&cyan)Cyan text(&)'
'(&orange)Orange text(&)'
'(&pink)Pink text(&)'
'(&gray)Gray text(&)'
'(&white)White text(&)'
| Variable | Value |
| --- | --- |
| `DISCORD_TOKEN` | bot token, with the Server Members and Presence intents enabled |
| `DISCORD_USER_ID` | your user id |
| `DISCORD_GUILD_ID` | a server both you and the bot are in |
// Semantic colors (theme-aware)
'(&primary)Primary color(&)'
'(&accent)Accent color(&)'
'(&muted)Muted text(&)'
'(&error)Error text(&)'
'(&success)Success text(&)'
'(&warning)Warning text(&)'
'(&info)Info text(&)'
Variables are declared in `src/env.ts`. Without them the widget shows your profile name as offline.
// Custom hex colors
'(&#ff6b6b)Custom color(&)'
```
## Analytics
### Background Colors
Add `bg-` prefix to any color:
```typescript
'(&bg-red)Red background(&)'
'(&bg-blue,white)Blue bg with white text(&)'
'(&bg-surface)Surface background(&)'
'(&bg-#333333)Custom bg color(&)'
```
### Text Styles
```typescript
'(&bold)Bold text(&)'
'(&italic)Italic text(&)'
'(&dim)Dimmed text (60% opacity)(&)'
'(&underline)Underlined text(&)'
'(&strikethrough)Strikethrough text(&)'
'(&strike)Strikethrough shorthand(&)'
'(&overline)Overlined text(&)'
```
### Inline Icons
```typescript
'(&icon, mdi:github) GitHub' // Inline icon, default size
'(&icon, mdi:trophy, 32) Winner' // Inline icon with a custom size in pixels
```
### Combining Styles
Combine multiple styles with commas:
```typescript
'(&bold,red)Bold red text(&)'
'(&italic,cyan,underline)Italic cyan underlined(&)'
'(&bg-blue,white,bold)Bold white on blue(&)'
'(&dim,strikethrough,gray)Dim gray strikethrough(&)'
```
## Line Types
### Basic Lines
```typescript
const lines: TerminalLine[] = [
{ type: 'command', content: 'ls -la' }, // With prompt prefix
{ type: 'output', content: 'File listing...' }, // Muted text
{ type: 'error', content: 'Error message' }, // Red with prefix
{ type: 'success', content: 'Success!' }, // Green with prefix
{ type: 'info', content: 'Information' }, // Primary with prefix
{ type: 'header', content: 'Section Title' }, // Bold heading
{ type: 'blank', content: '' }, // Empty line
{ type: 'divider', content: 'SECTION', id: 'section' }, // Horizontal divider with anchor ID
];
```
### Line Properties
All line types support these optional properties:
```typescript
{
type: 'output',
content: 'Hello world',
id: 'my-section', // Anchor ID for URL hash scrolling (e.g., /page#my-section)
inline: true, // Render inline with adjacent inline elements
delay: 500, // Delay before this line appears (ms)
}
```
### Button (Full-width interactive)
```typescript
{
type: 'button',
content: 'Click me',
icon: 'mdi:github', // Iconify icon
style: 'primary', // primary | accent | warning | error
href: 'https://github.com', // URL to navigate to
external: true, // Open in new tab (auto-detected for http/https)
inline: true, // Render as compact inline button
// OR
action: () => doSomething(), // Custom action
border: false, // Disable default border (default: true)
flex: true, // Grow to fill available space in a row group (default: false)
}
```
### Inline Elements
Multiple elements can be rendered on the same line using `inline: true`:
```typescript
// These will appear on the same line
{ type: 'output', content: 'Status:', inline: true },
{ type: 'success', content: 'Online', inline: true },
{ type: 'button', content: 'Refresh', icon: 'mdi:refresh', inline: true },
// Next line without inline breaks the group
{ type: 'blank', content: '' },
```
Supported inline types: `button`, `link`, `tooltip`, `progress`, `output`, `info`, `success`, `error`, `warning`
### Link (Inline clickable text)
```typescript
{
type: 'link',
content: 'Visit GitHub',
icon: 'mdi:github', // Optional icon
style: 'accent', // Styling
href: 'https://github.com',
external: true, // Open in new tab (auto-detected for http/https)
}
```
### Image
```typescript
{
type: 'image',
content: 'Caption text', // Optional caption
image: '/path/to/image.png',
imageAlt: 'Alt text',
imageWidth: 300, // Max width in pixels
}
```
### Card
```typescript
{
type: 'card',
content: 'Card body text with (&bold)formatting(&) support',
cardTitle: 'Card Title', // Optional header
cardFooter: 'Footer text', // Optional footer
icon: 'mdi:star', // Optional header icon
image: '/path/to/image.png', // Optional card image
style: 'primary', // Border accent color
display: 'flex', // flex | grid | block (controls children layout)
children: [ // Optional nested elements
{ type: 'button', content: 'Action', style: 'primary' }
],
cardWidth: '1/2', // Width (string fraction, decimal, or px)
cardHeight: 300, // Height (string fraction, decimal, or px)
cardFloat: 'center', // start | center | end
}
```
### Progress Bar
```typescript
{
type: 'progress',
content: 'Loading assets...', // Label above bar
progress: 75, // 0-100 percentage
progressLabel: '75%', // Custom label (defaults to percentage)
style: 'accent', // Bar color
}
```
### Accordion
```typescript
{
type: 'accordion',
content: '',
accordionItems: [
{ title: 'Section 1', content: 'Content for section 1 with (&cyan)colors(&)' },
{ title: 'Section 2', content: 'Content for section 2' },
],
accordionOpen: true, // First item open by default
style: 'primary', // Accent color
}
```
### Table
```typescript
{
type: 'table',
content: 'Table Title', // Optional title
tableHeaders: ['Name', 'Role', 'Status'],
tableRows: [
['Alice', 'Developer', '(&success)Active(&)'],
['Bob', 'Designer', '(&warning)Away(&)'],
],
style: 'accent', // Header color
}
```
### Tooltip
```typescript
{
type: 'tooltip',
content: 'Hover me', // Trigger text
tooltipText: 'This is helpful information!',
tooltipPosition: 'top', // top | bottom | left | right
style: 'info', // Tooltip border color
}
```
### Group
Groups allow you to arrange multiple elements together with custom layout:
```typescript
{
type: 'group',
content: '',
groupDirection: 'row', // row | column (default: row)
groupAlign: 'start', // start | center | end
groupGap: '1rem', // CSS gap value
groupExpand: true, // Expand children to fill width (default: false)
inline: true, // Render inline with other elements
children: [
{ type: 'output', content: 'Label:', inline: true },
{ type: 'button', content: 'Action', style: 'primary', inline: true },
{ type: 'link', content: 'More info', href: '/help', inline: true }
]
}
```
Groups support nested groups and all element types as children. Children are rendered using the same `TuiLine` component, ensuring consistent behavior.
## TUI Components
### TerminalTUI
Main terminal component:
```svelte
<TerminalTUI
lines={lines}
title="~/directory"
interactive={true}
speed="normal"
autoscroll={true}
enableCommands={true}
onComplete={() => console.log('Done!')}
/>
```
Props:
- `lines` - Array of TerminalLine objects
- `title` - Terminal window title
- `interactive` - Enable keyboard navigation
- `speed` - Typing speed preset or multiplier
- `autoscroll` - Auto-scroll as content types (default: true)
- `enableCommands` - Show the interactive command input (default: true)
- `onComplete` - Callback when typing animation finishes
### Anchor Scrolling
Add `id` to any line to create an anchor that can be linked to:
```typescript
{ type: 'divider', content: 'SKILLS', id: 'skills' },
```
Then link to it with `/portfolio#skills` - the page will scroll to that section after typing completes.
## Terminal API
The `TerminalTUI` component exposes a reactive API for programmatic control via the `terminal` bindable prop.
### Setup
```svelte
<script lang="ts">
import TerminalTUI from '$lib/components/TerminalTUI.svelte';
import type { TerminalAPI, TerminalLine } from '$lib';
let terminal = $state<TerminalAPI>();
let lines = $state<TerminalLine[]>([

## Theme System
Themes are defined as JSON files in `src/lib/assets/themes/`. Each theme contains colors for both dark and light modes. Shipped themes: Arch, Catppuccin, Wintry, Rose, and Cerberus (`src/lib/stores/theme.ts`).
### Theme File Structure
```json
{
"name": "Theme Name",
"icon": "arch",
"dark": {
"colors": {
"primary": "#89b4fa",
"secondary": "#313244",
"accent": "#a6e3a1",
"background": "#1e1e2e",
"backgroundLight": "#313244",
"text": "#cdd6f4",
"textMuted": "#a6adc8",
"border": "#45475a",
"terminal": "#1e1e2e",
"terminalPrompt": "#cba6f7",
"terminalUser": "#a6e3a1",
"terminalPath": "#89b4fa"
},
"colorMap": {
"red": "#f38ba8",
"green": "#a6e3a1",
"blue": "#89b4fa",
"primary": "var(--terminal-primary)",
"accent": "var(--terminal-accent)",
"muted": "var(--terminal-muted)"
}
},
"light": {
"colors": { },
"colorMap": { }
}
}
```
### Adding a New Theme
1. Create a new file: `src/lib/assets/themes/mytheme.theme.json`
2. Import it in `src/lib/stores/theme.ts`:
```typescript
import myTheme from '$lib/assets/themes/mytheme.theme.json';
```
3. Add it to the themes object:
```typescript
const themes: Record<ColorTheme, ThemeJson> = {
arch: archTheme,
catppuccin: catppuccinTheme,
mytheme: myTheme as ThemeJson
};
```
4. Update the `ColorTheme` type to include your theme name
### Theme-Specific Colors
Beyond the basic colors, themes include:
- `teal`, `sky`, `sapphire`, `lavender`
- `peach`, `maroon`, `mauve`
- `flamingo`, `rosewater`
```typescript
// These colors adapt to the current theme
'(&teal)Teal text(&)'
'(&lavender)Lavender text(&)'
'(&peach)Peach text(&)'
```
## Mobile Considerations
- Viewport height: Uses `100dvh` (dynamic viewport height) to properly handle mobile browser chrome
- Background color: A fallback dark background (`#1e1e2e`) is set on `html` and `body` to prevent white bars when the page content doesn't fill the viewport
- Overflow handling: Hidden horizontal scrollbar to prevent accidental horizontal scroll on mobile
