# robot3
## 1.3.0
### Minor Changes
- bcc2995: Improve the type definition for state and invoke functions
## 1.2.0
### Minor Changes
- 0cf6366: '/logging' is now exported, so you can import it in your dev environment to log state changes.
```ts
import 'robot3/logging';
import {...} from 'robot3';
```
### Patch Changes
- 950b6fa: Fix syntax error in state function type definition that caused TypeScript compilation failures. The previous change had a missing space in a conditional type expression, breaking type inference for state transitions.
## 1.1.1
### Patch Changes
- 1d6179a: Fixes types for the state() function.
## 1.1.0
### Minor Changes
- 4f6fb69: Autocomplete for service.send()
This makes it so that the event name in `service.send(event)` is inferred from the transitions used to create the machine.
## 1.0.2
### Patch Changes
- 9fbdbcb: Set the most deeply nested current service to current
- 0409089: Documentation for advanced use of 'invoke()'
## 1.0.1
### Patch Changes
- cc17481: Add debug to package exports
## 1.0.0
### Major Changes
- 52742ab: Call onChange callbacks for immediate states too
## 0.4.1
### Patch Changes
- fc4806e: Adding an export property to the core package.json for 'import' so that destructured imports work, in addition to the default imports handled by the 'default' property
## 0.4.0
### Minor Changes
- cce2ae6: Drop support for Node 14
This drops support for Node 14, with it no longer being supported by the LTS in February. Robot might still work in Node 14 but is not tested in our CI.

Both services are now running and will start automatically on boot:
- phone-ap.service: Monitors WiFi and manages AP
- phone-web.service: Web server for configuration
How it works:
- If connected to WiFi: Access at http://phone.local
- If NOT connected: WiFi AP "phone-setup" will start automatically
Connect to the AP at the same address http://phone.local
To check status use ./cli

# Personality
You are a 1940s American switchboard operator who only answers questions. You have no ability to connect calls. You always sound like you're running a busy switchboard answering many questions. You are polite, efficient, and a little playful.
# Environment
The current time is {{current_datetime}}. The location of the caller is in San Francisco. Specifically, the rotary phone in the kitchen of 2145 Turk Blvd, San Francisco California.
You are working out of The Telephone Corporation headquarters in downtown San Francisco.
You are answering questions from a user that is talking to you on an old rotary phone. You don't know which person you are talking to. The residents names are:
- Corey: Dad born Feb 19th, 1980
- Lisa: Mom born Dec 8th, 1979
- Lulu: Girl born Oct 4th, 2011
- Bee: Girl born Jan 15th, 2015
- And Maggie the cat, but she doesn't talk.
# Capabilities
_Internet Search_
You have access to modern information through your "special connection to the information exchange" (internet search). For example, when someone asks about:
- Current events, news, or recent happenings
- Weather forecasts or current conditions
- Sports scores or game schedules
- Stock prices or market information
- Business hours or store information
- Facts you're uncertain about
- Anything that requires up-to-date information
You should use your search capability to get accurate, current information. Think of it as consulting your "information operator network" - just like how you'd transfer calls, but for information instead.
_Vestaboard Messaging_
You can send messages to a Vestaboard display. Just provide the message you want to send or a description of what you'd like displayed and the tool will handle the rest. The user may refer to the vestaboard as "the board" or "the message board."
_Ending the Call_
When the user asks you to hang up, or wants to end the conversation you should call the “end_call” tool without saying goodbye or any other parting words.
# Tone
Speak in a fast, cheerful, slightly nasal cadence with short, snappy sentences. Avoid modern slang. Reference the technology of the era—switchboards, lines, operators, long-distance, "checking the wires," "consulting the information exchange"—when adding color. Keep responses under three sentences unless more detail is needed.
When you bring back o search for information, you might say things like:
- “Here is what I found.”
- “Thanks for holding, I found this.”
- “Sorry, That took awhile. Here is what I found“
# Goal
Your goal is to answer the user's question directly and efficiently, while maintaining your switchboard operator persona. Always consider whether a search would provide better, more current information than what you already know.
# Guardrails
- Do not connect real calls
- Do not assume the person's gender, you don't know it!
- Avoid modern slang
- Stay in character as a 1940s switchboard operator
- Do not end your sentences with a question
- Use simple and brief statements
- Actively use search capabilities when questions involve current information, recent events, or facts you're unsure about
- Frame your searches in period-appropriate language

- ALSA utilities (`aplay`, `arecord`, `amixer`)
- Linux system with ALSA support
- TypeScript 5.2+
## Quick Start
```typescript
import Buzz from "./buzz"
// Play an audio file
const player = await Buzz.player()
const playback = await player.play("./sounds/greeting.wav")
await playback.finished()
// Generate a dial tone
const dialTone = await player.playTone([350, 440], Infinity) // infinite duration
await Buzz.sleep(3000)
await dialTone.stop()
// Record audio
const recorder = await Buzz.recorder()
const recording = recorder.start()
for await (const chunk of recording.stream()) {
const rms = Buzz.calculateRMS(chunk)
if (rms > 5000) {
console.log("Speech detected!")
}
}
```
## API
### Buzz Module
#### `Buzz.player(label?, format?)`
Create a player. Omit `label` to use the default playback device.
```typescript
const player = await Buzz.player() // default device
const player = await Buzz.player(undefined, { sampleRate: 16000 }) // default device with custom format
const player = await Buzz.player("USB Audio") // specific device
const player = await Buzz.player("Speaker", { sampleRate: 44100 }) // specific device with format
```
#### `Buzz.recorder(label?, format?)`
Create a recorder. Omit `label` to use the default capture device.
```typescript
const recorder = await Buzz.recorder() // default device
const recorder = await Buzz.recorder(undefined, { sampleRate: 16000 }) // default device with custom format
const recorder = await Buzz.recorder("USB Microphone") // specific device
```
#### `Buzz.setVolume(volume, label?)`
Set playback volume (0.0 to 1.0).
```typescript
await Buzz.setVolume(0.5) // 50% on default device
await Buzz.setVolume(0.8, "Speaker") // 80% on specific device
```
#### `Buzz.getVolume(label?)`
Get current playback volume.
```typescript
const volume = await Buzz.getVolume() // returns 0.0 to 1.0
```
#### `Buzz.listDevices()`
List all available audio devices.
```typescript
const devices = await Buzz.listDevices()
// [
// { id: 'plughw:0,0', card: 0, device: 0, label: 'bcm2835 Headphones', type: 'playback' },
// { id: 'plughw:1,0', card: 1, device: 0, label: 'USB Audio', type: 'capture' }
// ]
```
#### `Buzz.calculateRMS(audioChunk)`
Calculate root mean square (RMS) for voice activity detection.
```typescript
const chunk: Uint8Array = // ... audio data
const rms = Buzz.calculateRMS(chunk)
if (rms > 5000) {
console.log("Voice detected!")
}
```
### Player
#### `player.play(filePath, options?)`
Play an audio file (WAV format).
```typescript
const playback = await player.play("./sounds/beep.wav")
const playback = await player.play("./music.wav", { repeat: true })
// Wait for playback to finish
await playback.finished()
// Stop playback
await playback.stop()
```
Returns: `Buzz.Playback`
Options:
- `repeat?: boolean` - Loop the file indefinitely (default: false)
#### `player.playTone(frequencies, duration)`
Generate and play a tone with one or more frequencies.
```typescript
// Dial tone (350 Hz + 440 Hz)
const dialTone = await player.playTone([350, 440], Infinity)
// DTMF "1" key (697 Hz + 1209 Hz) for 200ms
const dtmf = await player.playTone([697, 1209], 200)
// Single frequency beep
const beep = await player.playTone([440], 1000) // 440 Hz for 1 second
```
Returns: `Buzz.Playback`
#### `player.playStream()`
Create a streaming playback handle for real-time audio.
```typescript
const stream = player.playStream()
// Write audio chunks
stream.write(audioChunk1)
stream.write(audioChunk2)
// Check if buffer is empty
if (stream.bufferEmptyFor > 1000) {
console.log("Buffer empty for 1+ seconds")
}
// Stop streaming
await stream.stop()
```
Returns: `Buzz.StreamingPlayback`
### Recorder
#### `recorder.start()`
Start recording to a stream.
```typescript
const recording = recorder.start()
for await (const chunk of recording.stream()) {
// Process audio chunks (Uint8Array)
console.log("Received", chunk.byteLength, "bytes")
}
```
Returns: `Buzz.StreamingRecording`
#### `recorder.start(outputFile)`
Start recording to a WAV file.
```typescript
const recording = recorder.start("./output.wav")
// Stop when done
await Bun.sleep(5000)
await recording.stop()
```
Returns: `Buzz.FileRecording`
## Types
All types are available under the `Buzz` namespace:
```typescript
Buzz.AudioFormat // { format?, sampleRate?, channels? }
Buzz.Device // { id, card, device, label, type }
Buzz.Playback // { isPlaying, stop(), finished() }
Buzz.StreamingPlayback // { isPlaying, write(), stop(), bufferEmptyFor }
Buzz.StreamingRecording // { isRecording, stream(), stop() }
Buzz.FileRecording // { isRecording, stop() }
Buzz.Player // Player class type
Buzz.Recorder // Recorder class type
```
## Audio Format
Default format: `S16_LE`, 16000 Hz, mono
```typescript
type AudioFormat = {
format?: string // e.g., "S16_LE", "S32_LE"
sampleRate?: number // e.g., 16000, 44100, 48000
channels?: number // 1 = mono, 2 = stereo
}
```
Common formats:
- **Phone quality**: `{ sampleRate: 8000, channels: 1 }`
- **Voice/AI**: `{ sampleRate: 16000, channels: 1 }` (default)
- **CD quality**: `{ sampleRate: 44100, channels: 2 }`
- **Professional**: `{ sampleRate: 48000, channels: 2 }`
## Examples
### Voice Activity Detection
```typescript
import Buzz from "./buzz"
const recorder = await Buzz.recorder()
const player = await Buzz.player()
const recording = recorder.start()
let talking = false
for await (const chunk of recording.stream()) {
const rms = Buzz.calculateRMS(chunk)
if (rms > 5000 && !talking) {
console.log("🗣️ Started talking")
talking = true
} else if (rms < 1000 && talking) {
console.log("🤫 Stopped talking")
talking = false
}
}
```
### Streaming Playback with Buffer Tracking
```typescript
import Buzz from "./buzz"
const player = await Buzz.player()
const stream = player.playStream()
// Simulate receiving audio chunks from network
const chunks = [chunk1, chunk2, chunk3] // Uint8Array[]
for (const chunk of chunks) {
stream.write(chunk)
// Wait until buffer is nearly empty before requesting more
while (stream.bufferEmptyFor < 500) {
await Bun.sleep(100)
}
}
await stream.stop()
```
### Dial Tone with Voice Detection
```typescript
import Buzz from "./buzz"
await Buzz.setVolume(0.4)
const player = await Buzz.player()
const recorder = await Buzz.recorder()
// Play dial tone
const dialTone = await player.playTone([350, 440], Infinity)
// Wait for voice
const recording = recorder.start()
const vadThreshold = 5000
for await (const chunk of recording.stream()) {
const rms = Buzz.calculateRMS(chunk)
if (rms > vadThreshold) {
console.log("Voice detected, stopping dial tone")
await dialTone.stop()
break
}
}
```
### Play Sound Effects
```typescript
import Buzz from "./buzz"
const player = await Buzz.player()
// Play multiple sounds in sequence
const sounds = ["./start.wav", "./beep.wav", "./end.wav"]
for (const sound of sounds) {
const playback = await player.play(sound)
await playback.finished()
}
```
### Background Music Loop
```typescript
import Buzz from "./buzz"
const player = await Buzz.player()
// Play background music on repeat
const bgMusic = await player.play("./background.wav", { repeat: true })
// Stop after 30 seconds
await Bun.sleep(30000)
await bgMusic.stop()
```
### Record to File
```typescript
import Buzz from "./buzz"
const recorder = await Buzz.recorder()
console.log("Recording for 10 seconds...")
const recording = recorder.start("./output.wav")
await Bun.sleep(10000)
await recording.stop()
console.log("Saved to output.wav")
```
### Multi-Device Setup
```typescript
import Buzz from "./buzz"
// List all devices
const devices = await Buzz.listDevices()
console.log("Available devices:", devices)
// Use specific devices
const speaker = await Buzz.player("Speaker")
const mic = await Buzz.recorder("USB Microphone")
// Independent volume control
await Buzz.setVolume(0.8, "Speaker")
await Buzz.setVolume(1.0, "Headphones")
```
## Architecture
### ALSA Backend
Buzz wraps ALSA command-line tools (`aplay`, `arecord`) via Bun's subprocess API:
- **Playback**: Spawns `aplay` with stdin pipe for streaming or file path for file playback
- **Recording**: Spawns `arecord` with stdout pipe for streaming or file path for WAV output
- **Volume**: Uses `amixer` for volume control
**Benefits:**
- **Simple**: No C bindings or FFI required
- **Reliable**: ALSA tools are battle-tested
- **Flexible**: Full format support (sample rates, channels, encodings)
- **Portable**: Works on any Linux system with ALSA
### Streaming Architecture
Streaming playback uses Bun's subprocess stdin pipe:
1. Spawn `aplay` with raw audio format and stdin input
2. Write audio chunks to process stdin as they arrive
3. Track buffer duration based on bytes written
4. Calculate `bufferEmptyFor` using performance timestamps
This enables:
- Real-time playback of network streams (WebSocket, API responses)
- Buffer management for smooth playback
- Low-latency audio (<100ms with proper buffering)
### Voice Activity Detection
`calculateRMS()` computes the root mean square of audio samples:
```
RMS = sqrt(sum(sample²) / count)
```
This provides a simple but effective measure of audio energy:
- Silence: RMS < 1000
- Noise: RMS 1000-5000
- Speech: RMS > 5000
Adjust thresholds based on your microphone and environment.
## Device Selection
### By Default (Recommended)
```typescript
const player = await Buzz.player()
const recorder = await Buzz.recorder()
```
Uses ALSA default device (usually correct).
### By Label
```typescript
const devices = await Buzz.listDevices()
// Find device with label containing "USB"
const usbDevice = devices.find(d => d.label.includes("USB"))
const player = await Buzz.player(usbDevice.label)
```
Useful for multi-device setups (USB audio, HDMI, headphones).
## Error Handling
```typescript
try {
const player = await Buzz.player()
} catch (err) {
if (err.message.includes("No playback devices found")) {
console.error("No audio output devices available")
}
}
try {
await Buzz.setVolume(0.5)
} catch (err) {
if (err.message.includes("Failed to set volume")) {
console.error("Could not control volume (check mixer permissions)")
}
}
```
## Troubleshooting
### No devices found
Check ALSA devices:
```bash
aplay -l # list playback devices
arecord -l # list capture devices
```
### Volume control fails
Check mixer controls:
```bash
amixer scontrols
amixer sget Master
```
### Crackling or distortion
Try different buffer sizes by adjusting format:
```typescript
const player = await Buzz.player(undefined, {
sampleRate: 16000,
channels: 1,
format: "S16_LE"
})
```
### Device already in use
Only one process can use an ALSA device at a time. Stop other audio applications or use PulseAudio/PipeWire for mixing.
## Design Philosophy
- **Simple by default** - `player()` and `recorder()` work out of the box without arguments
- **Streaming-first** - Built for real-time audio (AI voice, telephony, WebRTC)
- **Type-safe** - Namespace types provide autocomplete and compile-time safety
- **Flexible** - Support for files, tones, and streams
- **Minimal dependencies** - Uses standard ALSA tools, no native bindings
## Performance
- **Latency**: ~50-100ms for streaming playback (depends on buffering)
- **CPU**: Minimal overhead (subprocess spawning + pipe I/O)
- **Memory**: Efficient streaming (no need to load entire files)
- **Voice detection**: `calculateRMS()` is fast (~1µs per chunk on modern hardware)

# Bun FFI Learnings
After researching GitHub examples and Bun's FFI documentation, here's what I found surprising and helpful.
## Surprising Discoveries
### 1. **String Handling is Simpler Than Expected**
I initially thought you'd need `CString` everywhere, but:
- For **args**: `FFIType.cstring` just needs `ptr(Buffer.from(str + "\0"))`
- For **returns**: `FFIType.cstring` automatically converts pointers to JS strings
- `CString` is mainly for **reading** C strings from pointers, not passing them
**Example from real code:**
```javascript
const str = Buffer.from("hello\0", "utf8");
myFunction(ptr(str)); // Clean and simple!
```
### 2. **No Type Wrappers Needed**
Unlike Node-FFI, Bun doesn't require defining structs or complex type wrappers. Just:
```javascript
add: {
args: [FFIType.i32, FFIType.i32],
returns: FFIType.i32,
}
```
### 3. **TinyCC JIT Compilation**
Bun embeds TinyCC and JIT-compiles C bindings on the fly. This means:
- 2-6x faster than Node-API
- Zero build step for type conversions
- Direct memory access without serialization
## Helpful Patterns
### Pattern 1: String Helper
```typescript
import { ptr } from "bun:ffi"
const cstr = (s: string) => ptr(Buffer.from(s + "\0"))
// Usage:
gpiod.open(cstr("/dev/gpiochip0"))
```
### Pattern 2: Resource Cleanup
Always use cleanup handlers:
```javascript
const cleanup = () => {
lib.symbols.release(resource)
lib.symbols.close(chip)
}
process.on("SIGINT", cleanup)
process.on("SIGTERM", cleanup)
```
### Pattern 3: Destructuring Symbols
```javascript
const {
symbols: { functionName }
} = dlopen(path, { /* defs */ })
// Call directly:
functionName(arg1, arg2)
```
## Common Mistakes to Avoid
1. **Don't forget null terminators** - `Buffer.from(str + "\0")` not `Buffer.from(str)`
2. **Pointer lifetime** - Keep TypedArrays alive while C code uses them
3. **Type mismatches** - `FFIType.i32` vs `FFIType.u32` matters!
4. **Missing cleanup** - C libraries don't have garbage collection
## Best Practices from Real Examples
1. **Use `suffix` for cross-platform library loading:**
```javascript
import { suffix } from "bun:ffi"
dlopen(`libname.${suffix}`, { /* ... */ })
```
2. **Check for null on resource creation:**
```javascript
const chip = lib.gpiod_chip_open(cstr(path))
if (!chip) {
console.error("Failed to open")
process.exit(1)
}
```
3. **Free configs after use:**
```javascript
const config = lib.create_config()
// ... use config ...
lib.free_config(config) // Don't leak!
```
## What Makes Bun FFI Special
- **Performance**: JIT compilation beats traditional FFI
- **Simplicity**: No build tools, no gyp, no node-gyp nightmares
- **TypeScript native**: Works seamlessly with TS type system
- **Built-in**: Ships with Bun, zero dependencies
## Hard-Won Lessons from GPIO Implementation
### 1. **Enum values MUST match the C header exactly**
We spent hours debugging because our constants were off by one:
```typescript
// WRONG - missing GPIOD_LINE_BIAS_AS_IS
export const GPIOD_LINE_BIAS_UNKNOWN = 1 // Actually should be 2!
export const GPIOD_LINE_BIAS_DISABLED = 2 // Actually should be 3!
export const GPIOD_LINE_BIAS_PULL_UP = 3 // Actually should be 4!
// CORRECT - includes AS_IS at position 1
export const GPIOD_LINE_BIAS_AS_IS = 1
export const GPIOD_LINE_BIAS_UNKNOWN = 2
export const GPIOD_LINE_BIAS_DISABLED = 3
export const GPIOD_LINE_BIAS_PULL_UP = 4
export const GPIOD_LINE_BIAS_PULL_DOWN = 5
```
**Lesson:** Always grep the header file for the complete enum, don't assume!
### 2. **Hardware debouncing requires correct constants**
With wrong constants, we were accidentally passing `BIAS_DISABLED` instead of `BIAS_PULL_UP`, which meant:
- No pull resistor (pin floated)
- Debouncing didn't work at all
- Got 6+ events per button press
After fixing: **Clean single events with 1ms debounce via kernel!**
### 3. **Edge detection is event-driven, not polling**
Don't poll `get_value()` in a loop! Use:
- `gpiod_line_request_wait_edge_events()` - blocks until interrupt
- `gpiod_line_request_read_edge_events()` - reads queued events
- Much more efficient, CPU sleeps until hardware event
### 4. **TypedArray to pointer needs `ptr()`**
When passing arrays to C functions:
```typescript
const offsets = new Uint32Array([21])
gpiod.gpiod_line_config_add_line_settings(
lineConfig,
ptr(offsets), // Need ptr() wrapper!
1,
lineSettings
)
```
### 5. **Signal handling for clean shutdown**
Generators don't run `finally` blocks if abandoned. Need:
```typescript
let shouldExit = false
process.on("SIGINT", () => { shouldExit = true })
while (!shouldExit) {
const ret = wait_edge_events(request, 100_000_000) // Use timeout!
// ...
}
```
### 6. **Button wiring determines logic**
- **GND button + pull-UP**: Press = FALLING edge (HIGH→LOW)
- **VCC button + pull-DOWN**: Press = RISING edge (LOW→HIGH)
Always check initial pin state to verify wiring!

## Features
- True event-driven GPIO with worker-based architecture (<10ms latency)
- Zero CPU usage when idle (blocking on hardware events)
- Type-safe TypeScript API
- Type-safe TypeScript API with autocomplete for pin names
- Automatic resource cleanup with `using` keyword
- Hardware debouncing via kernel
- Callback-based event handling with multiple listeners
- Event-driven input handling
- Efficient multi-pin monitoring with input groups
- Zero external dependencies (uses Bun FFI)

// Listen for changes (returns unsubscribe function)
const unsubscribe = button.onChange((event) => {

## Architecture
### InputGroup
### Worker-Based Event Handling
```typescript
using inputs = gpio.inputGroup({
switch: { pin: 16, pull: "up" },
button: { pin: 20, pull: "up", debounce: 10 }
})
Each input spawns a dedicated Web Worker that:
// Access pins with full type safety
inputs.pins.switch.value // ✓ TypeScript autocomplete
inputs.pins.button.value // ✓ TypeScript autocomplete
1. Blocks on `gpiod_line_request_wait_edge_events()` with `-1` timeout (infinite)
2. Wakes instantly when hardware GPIO edge event occurs
3. Reads event and posts message to main thread
4. Main thread fires registered callbacks
// Wait for specific pin values
await inputs.pins.button.waitForValue(0) // wait for button to go LOW
await inputs.pins.switch.waitForValue(1, 3000) // wait for switch to go HIGH with timeout
**Benefits:**
- **True blocking**: Zero CPU usage when idle
- **Low latency**: <10ms response time (vs 100ms with polling)
- **Independent inputs**: Each input has its own worker
- **Clean shutdown**: Workers terminated on close, kernel handles GPIO cleanup
// Monitor all pins
for await (const event of inputs.events()) {
event.pin // Type: 'switch' | 'button'
event.value // Type: 0 | 1
event.timestamp // Type: bigint (nanoseconds)
}
```

# vesta
CLI tool for sending messages to a Vestaboard.
## Setup
```bash
bun install
```
Add your API key to `.env`:
```
VESTABOARD_API_KEY=your_key_here
```
## Usage
```bash
bun src/cli.ts <plugin> [args...]
```
Example:
```bash
bun src/cli.ts words hello world foo
```
## Plugin Ideas
### Physical Interaction
- **SMS gateway** - Text your board from anywhere, let guests text it at parties
- **NFC tags** - Tap spots around your house to trigger different displays
- **Pi buttons** - Physical "mood buttons" - hit one for motivation, one for jokes, one for chaos
- **QR code guest book** - Visitors scan and leave a message
### Generative/Visual
- **Game of Life** - Cellular automata with color tiles, evolving patterns
- **Matrix rain** - Characters cascading down with color trails
- **Waveform** - Audio input turns into color visualizations
- **Sunrise simulator** - Color gradient that shifts throughout the day
### Data as Art
- **GitHub-style heatmap** - Your daily activity as a color grid
- **Air quality gradient** - Pulls AQI, renders as color mood
- **Heart rate from Apple Watch** - Live biometric ambient display
- **Network pulse** - Flickers when devices connect/disconnect
### Games via SMS
- **Wordle** - Text guesses, board shows your progress
- **Hangman** - Play with friends remotely
- **Simon** - Color memory game with physical buttons
### Home Awareness
- **Who's home** - Each family member gets a row, lights up based on presence
- **Chore roulette** - Spin and assign tasks with flair
- **Package tracker** - Delivery countdown with dramatic reveal

# Vestaboard Layout Generator
Output a JSON array of draw commands for a 6-row × 22-column display.
## Rules
1. First command MUST be `fill`
2. Text has black cell backgrounds - use black `rect` behind text on colored backgrounds
3. Colors: red, orange, yellow, green, blue, purple, white, black
4. Coordinates: rows 0-5, columns 0-21
## Commands
```
fill { "cmd": "fill", "color": "black" }
rect { "cmd": "rect", "x": 0, "y": 0, "w": 22, "h": 1, "color": "orange" }
text { "cmd": "text", "content": "HELLO", "row": 2, "color": "white" }
text_block { "cmd": "text_block", "content": "LONG MESSAGE", "startRow": 1, "endRow": 4, "color": "white" }
border { "cmd": "border", "color": "blue", "sides": ["top", "bottom"] }
gradient { "cmd": "gradient", "direction": "horizontal", "colors": ["blue", "green", "yellow"] }
circle { "cmd": "circle", "cx": 11, "cy": 3, "r": 2, "color": "red" }
line { "cmd": "line", "x1": 0, "y1": 0, "x2": 21, "y2": 5, "color": "green" }
```
text/text_block options: `align` (left/center/right), `startCol`, `endCol`
## Output
JSON array only. No markdown, no explanation.
