webui: add dark mode support to demo server

Core Component Dark Mode Support:
- sketch-timeline.ts: Welcome box, loading indicators, thinking bubbles, navigation
- sketch-tool-card-base.ts: Status icons, elapsed time, hover states, details panel
- All 14 sketch-tool-card-* components: Consistent dark styling for tool results

Demo System Infrastructure:
- Enhanced demo runner (demo.html) with complete dark theme CSS variables
- Added sketch-theme-toggle integration in sidebar for easy theme switching
- Extended demo-fixtures utilities with semantic color system (8 new CSS variables)
- Comprehensive color mappings: backgrounds, text, borders, controls, buttons

Demo File Compatibility (13 files updated):
- Fixed 60+ instances of hardcoded colors across all demo components
- Replaced light-mode-only colors (#24292f, #f6f8fa, etc.) with CSS variables
- Updated text colors, backgrounds, borders for proper contrast in both themes
- Maintained visual hierarchy while ensuring accessibility

Technical Implementation:
- CSS custom properties system with automatic :root/.dark theme switching
- GitHub-inspired dark color palette for professional appearance
- Smooth 0.2s transitions for seamless theme changes
- Semantic variable naming for maintainability and consistency

Key Features Added:
- Theme toggle accessible from any demo (no need to navigate to Theme Toggle demo)
- Complete visual consistency between light and dark modes
- Proper contrast ratios throughout for accessibility
- Tool card demos showcase dark mode styling with realistic content

Components Updated:
Timeline: Welcome messages, loading states, thinking indicators, jump button
Tool Cards: Status icons, input/output display, hover states, detailed views
Demos: Labels, backgrounds, instruction panels, control elements, text content

The demo system now provides a complete, professional dark mode experience
that matches modern development tool standards with excellent usability
and visual consistency across all components and demonstrations.

Sketch

Sketch is an agentic coding tool. It draws the 🦉

🚀 Overview

Sketch runs in your terminal, has a web UI, understands your code, and helps you get work done. To keep your environment pristine, sketch starts a docker container and outputs its work onto a branch in your host git repository.

Sketch helps with most programming environments, but Sketch has extra goodies for Go.

📋 Quick Start

Install via GitHub Releases

Grab the most recent nightly release.

Update by running sketch -update.

Build from source

Clone this repo, and then run:

$ make
$ ./sketch

🔧 Requirements

Currently, Sketch runs on MacOS and Linux. It uses Docker for containers.

Platform	Installation
MacOS	`brew install colima` (or OrbStack or Docker Desktop)
Linux	`apt install docker.io` (or equivalent for your distro)
WSL2	Install Docker Desktop for Windows (docker entirely inside WSL2 is tricky)

The sketch.dev service is used to provide access to an LLM service and give you a way to access the web UI from anywhere.

📖 User Guide

Getting Started

Start Sketch by running sketch in a Git repository. It will open your browser to the Sketch chat interface, but you can also use the CLI interface. Use -open=false if you want to use just the CLI interface.

Ask Sketch about your codebase or ask it to implement a feature. It may take a little while for Sketch to do its work, so hit the bell (🔔) icon to enable browser notifications. We won't spam you or anything; it will notify you when the Sketch agent's turn is done, and there's something to look at.

How Sketch Works

When you start Sketch, it:

Creates a Dockerfile
Builds it
Copies your repository into it
Starts a Docker container with the "inside" Sketch running

This design lets you run multiple sketches in parallel since they each have their own sandbox. It also lets Sketch work without worry: it can trash its own container, but it can't trash your machine.

Sketch's agentic loop uses tool calls (mostly shell commands, but also a handful of other important tools) to allow the LLM to interact with your codebase.

Getting Your Git Changes Out

Sketch is trained to make Git commits. When those happen, they are automatically pushed to the git repository where you started sketch with branch names sketch/*.

Finding Sketch branches:

git branch -a --sort=creatordate | grep sketch/ | tail

The UI keeps track of the latest branch it pushed and displays it prominently. You can use standard Git workflows to pull those branches into your workspace:

git cherry-pick $(git merge-base origin/main sketch/foo)

or merge the branch

git merge sketch/foo

or reset to the branch

git reset --hard sketch/foo

Ie use the same workflows you would if you were pulling in a friend's Pull Request.

Advanced: You can ask Sketch to git fetch sketch-host and rebase onto another commit. This will also fetch where you started Sketch, and we do a bit of "git fetch refspec configuration" to make origin/main work as a git reference.

Don't be afraid of asking Sketch to help you rebase, merge/squash commits, rewrite commit messages, and so forth; it's good at it!

Reviewing Diffs

The diff view shows you changes since Sketch started. Leaving comments on lines adds them to the chat box, and, when you hit Send (at the bottom of the page), Sketch goes to work addressing your comments.

Connecting to Sketch's Container

You can interact directly with the container in three ways:

Web UI Terminal: Use the "Terminal" tab in the UI
SSH: Look at the startup logs or click the information icon to see a command like ssh sketch-ilik-eske-tcha-lott. We have automatically configured your SSH configuration to make these special hostnames work.
Visual Studio Code: Look for a command line or magic link behind the information icon, or when Sketch starts up. This starts a new VSCode session "remoted into" the container. You can edit the code, use the terminal, review diffs, and so forth.

Using SSH (and/or VSCode) allows you to forward ports from the container to your machine. For example, if you want to start your development webserver, you can do something like this:

# Forward container port 8888 to local port 8000
ssh -L8000:localhost:8888 sketch-ilik-epor-tfor-ward go run ./cmd/server

This makes http://localhost:8000/ on your machine point to localhost:8888 inside the container.

Using Browser Tools

You can ask Sketch to browse a web page and take screenshots. There are tools both for taking screenshots and "reading images", the latter of which sends the image to the LLM. This functionality is handy if you're working on a web page and want to see what the in-progress change looks like.

❓ FAQ

"No space left on device"

Docker images, containers, and so forth tend to pile up. Ask Docker to prune unused images and containers:

docker system prune -a

🛠️ Development

See CONTRIBUTING.md for development guidelines.

📄 Open Source

Sketch is open source. It is right here in this repository! Have a look around and mod away.

If you want to run Sketch entirely without the sketch.dev service, you can set the flag -skaband-addr="" and then provide an ANTHROPIC_API_KEY environment variable. (More LLM services coming soon!)
