+
+            IMPORTANT: Distinguish between:
+            - Device/firmware bugs (crashes, reboots, lockups, radio/GPS/display/power issues) - these need device logs
+            - Build/release/packaging issues (missing files, CI failures, download problems) - these do NOT need device logs
+            - Documentation or website issues - these do NOT need device logs
+
+            If this is a device/firmware bug, request device logs and explain how to get them:
+
+            Web Flasher logs:
+            - Go to https://flasher.meshtastic.org
+            - Connect the device via USB and click Connect
+            - Open the device console/log output, reproduce the problem, then copy/download and attach/paste the logs
+
+            Meshtastic CLI logs:
+            - Run: meshtastic --port <serial-port> --noproto
+            - Reproduce the problem, then copy/paste the terminal output
+
+            Also request key context if missing: device model/variant, firmware version, region, steps to reproduce, expected vs actual.
+
+            Respond ONLY with valid JSON (no markdown, no code fences):
+            {"complete": true, "comment": "", "label": "none"}
+            OR
+            {"complete": false, "comment": "Your helpful comment", "label": "needs-logs"}
+
+            Use "needs-logs" ONLY if this is a device/firmware bug AND no logs are attached.
+            Use "needs-info" if basic info like firmware version or steps to reproduce are missing.
+            Use "none" if the issue is complete, is a feature request, or is a build/CI/packaging issue.
+
+            Title: ${{ github.event.issue.title }}
+            Body: ${{ github.event.issue.body }}
+          system-prompt: You are a helpful assistant that triages GitHub issues. Be conservative with labels. Only request device logs for actual device/firmware bugs, not for build/release/CI issues.

+# Meshtastic OLED Emulator
+
+A Vue.js component and TypeScript library for emulating SSD1306/SH1106 OLED displays used in Meshtastic devices. This allows firmware UI development and testing directly in the browser.
+
+## Features
+
+- **Same API as firmware**: Uses the same `OLEDDisplay` API as esp8266-oled-ssd1306 library
+- **Multiple display sizes**: 128x64, 128x32, 64x48, 128x128
+- **Realistic rendering**: Pixel glow, OLED color tints (blue, white, yellow/blue dual)
+- **XBM image support**: Render firmware icons and images
+- **Font rendering**: Bitmap font support with text alignment
+- **Vue 3 component**: Easy integration with Vue applications
+
+## Installation
+
+```bash
+npm install @meshtastic/oled-emulator
+```
+
+## Quick Start
+
+```vue
+<script setup lang="ts">
+import { ref, onMounted } from "vue";
+import {
+  OLEDDisplay,
+  OLEDEmulator,
+  ArialMT_Plain_10,
+} from "@meshtastic/oled-emulator";
+
+// Create display matching firmware
+const display = ref(new OLEDDisplay("128x64"));
+
+onMounted(() => {
+  display.value.setFont(ArialMT_Plain_10);
+  display.value.clear();
+  display.value.drawString(10, 10, "Hello Mesh!");
+  display.value.drawRect(5, 5, 118, 54);
+  display.value.fillCircle(64, 32, 15);
+});
+</script>
+
+<template>
+  <OLEDEmulator
+    :display="display"
+    :pixel-scale="4"
+    preset="ssd1306-blue"
+    :enable-glow="true"
+  />
+</template>
+```
+
+## OLEDDisplay API
+
+The `OLEDDisplay` class provides the same methods as the firmware's display library:
+
+```typescript
+const display = new OLEDDisplay("128x64");
+
+// Basic drawing
+display.clear();
+display.setPixel(x, y);
+display.drawLine(x0, y0, x1, y1);
+display.drawRect(x, y, width, height);
+display.fillRect(x, y, width, height);
+display.drawCircle(x, y, radius);
+display.fillCircle(x, y, radius);
+
+// Text
+display.setFont(ArialMT_Plain_10);
+display.setTextAlignment("TEXT_ALIGN_CENTER");
+display.drawString(x, y, "Hello");
+display.drawStringMaxWidth(x, y, maxWidth, "Long text...");
+const width = display.getStringWidth("text");
+
+// Images (XBM format)
+display.drawXbm(x, y, width, height, imageData);
+
+// Colors
+display.setColor("WHITE"); // or 'BLACK', 'INVERSE'
+
+// Buffer access (for custom rendering)
+const buffer = display.getBuffer(); // Uint8Array
+```
+
+## Display Presets
+
+The emulator includes several realistic display presets:
+
+| Preset                | Description                     |
+| --------------------- | ------------------------------- |
+| `ssd1306-blue`        | Classic blue OLED (default)     |
+| `ssd1306-white`       | White OLED                      |
+| `ssd1306-yellow-blue` | Dual-color (top 16 rows yellow) |
+| `sh1106`              | SH1106 style                    |
+| `sh1107`              | SH1107 128x128                  |
+| `ssd1306-64x48`       | Small 64x48 display             |
+| `ssd1306-128x32`      | Wide 128x32 display             |
+
+## Screen Renderers
+
+Pre-built screen renderers matching firmware UI:
+
+```typescript
+import { ScreenRenderers } from "@meshtastic/oled-emulator";
+
+// Boot screen
+ScreenRenderers.drawBootScreen(display, "2.5.0");
+
+// Node info screen
+ScreenRenderers.drawNodeInfoScreen(display, {
+  shortName: "MESH",
+  longName: "My Node",
+  nodeId: "!abcd1234",
+  lastHeard: "2m ago",
+  snr: 12.5,
+});
+
+// Message screen
+ScreenRenderers.drawMessageScreen(display, {
+  from: "Alice",
+  text: "Hello from the mesh!",
+  time: "14:32",
+  channel: "LongFast",
+});
+
+// And more: drawGPSScreen, drawNodeListScreen, drawSystemScreen, drawCompassScreen
+```
+
+## Development
+
+```bash
+# Install dependencies
+npm install
+
+# Run development server
+npm run dev
+
+# Build library
+npm run build
+```
+
+## Future: Protocol Bridge
+
+A future enhancement will allow connecting this emulator to a real Meshtastic firmware instance (running on native/portduino), enabling live framebuffer streaming over WebSocket for real-time display mirroring.
