\"| GET[\"GET /api/images/:id\"]\n GET --> Blob\n```\n\n1. **Capture** — a hidden ``\n element opens the front-facing camera on iOS and Android.\n2. **Compress in-browser** — images are downscaled to max 1600px and re-encoded\n as JPEG at quality 0.82 before upload. Keeps uploads fast on cellular.\n3. **Upload** — `POST /api/images` with a multipart form. Server validates MIME\n type, stores bytes in `std/blob` under `chat-images/v1/{id}`, stores\n metadata in a new `chat_images_v1` SQLite table.\n4. **Post to chat** — the server then calls the existing `insertMessage()` to\n append a text message of the form `📷 /api/images/{id}`. This means the\n image is delivered to every other client through the **existing** SSE\n stream — zero changes to the message pipeline.\n5. **View** — `GET /api/images/:id` streams the bytes back with an\n `immutable` cache header.\n\n## Mobile UX notes\n\n- `capture=\"user\"` → front camera on iPhone/Android.\n- `accept=\"image/*\"` → also allows picking from the gallery if the user prefers.\n- `font-size: 16px` on any input (inherited from the app) avoids iOS zoom-on-focus.\n- Button is large (`min-h-10`, rounded pill) for easy thumb-tapping.\n- EXIF orientation handled via `createImageBitmap({ imageOrientation: 'from-image' })`.\n- Error state shows as a small inline toast above the button so it doesn't\n shift the layout.\n\n## Rendering images inline (future / optional)\n\nCurrently, images show up in the chat as a text line `📷 /api/images/123`. To\nrender them as real `` tags, `MessageList.tsx` could be taught to detect\nthis prefix and render accordingly. That change is **intentionally not made\nhere** so this branch stays orthogonal to any concurrent work on `MessageList`.\n\nA one-liner enhancement once merged:\n\n```tsx\n// In MessageList.tsx, inside the message map:\nconst imageMatch = msg.text.match(/^📷\\s+(\\/api\\/images\\/\\d+)/);\nif (imageMatch) {\n return

;\n}\n```\n\n## Storage\n\n- **Bytes**: `std/blob` at `chat-images/v1/{id}`\n- **Metadata**: SQLite table `chat_images_v1` (brand new — no migration of\n existing tables)\n- **Limits**: 8 MB max upload (enforced on both client post-compression and\n server). MIME allowlist: jpeg, png, webp, heic, heif. `application/octet-stream`\n from iOS camera is normalized to `image/jpeg`.\n",[],[228],"76fa6e6e-39cb-11f1-ad8a-42b51c65c3df","types.ts","76fa6f54-39cb-11f1-ad8a-42b51c65c3df","cf64b4d0-27e7-4acf-a35d-a8c97fbb846d",["D",1776368146229],"export interface Message {\n id: number;\n text: string;\n createdAt: string; // ISO timestamp\n}\n",[],[242,235],"shared","9aea6116-39cc-11f1-ae12-42b51c65c3df","sound.ts","9aea6198-39cc-11f1-ae12-42b51c65c3df",20,["D",1776368636019],"/**\n * Generate a simple beep sound using Web Audio API\n * Safe, no dependencies, works in all modern browsers\n */\nexport function playBeep(options?: {\n frequency?: number;\n duration?: number;\n volume?: number;\n}) {\n const freq = options?.frequency ?? 800; // Hz\n const dur = options?.duration ?? 200; // ms\n const vol = options?.volume ?? 0.3; // 0-1\n\n const audioContext = new (window.AudioContext || (window as any).webkitAudioContext)();\n const oscillator = audioContext.createOscillator();\n const gainNode = audioContext.createGain();\n\n oscillator.connect(gainNode);\n gainNode.connect(audioContext.destination);\n\n oscillator.frequency.value = freq;\n oscillator.type = 'sine';\n\n gainNode.gain.setValueAtTime(vol, audioContext.currentTime);\n gainNode.gain.exponentialRampToValueAtTime(0.01, audioContext.currentTime + dur / 1000);\n\n oscillator.start(audioContext.currentTime);\n oscillator.stop(audioContext.currentTime + dur / 1000);\n}\n\n/**\n * Play a notification sound (higher pitch, short duration)\n */\nexport function playNotification() {\n playBeep({ frequency: 1000, duration: 150, volume: 0.3 });\n}\n\n/**\n * Play a success sound (two ascending beeps)\n */\nexport function playSuccess() {\n playBeep({ frequency: 600, duration: 100, volume: 0.25 });\n setTimeout(() => playBeep({ frequency: 900, duration: 100, volume: 0.25 }), 120);\n}\n\n/**\n * Play a random sound from a selection\n */\nexport function playRandom() {\n const sounds = [playNotification, playSuccess];\n const randomSound = sounds[Math.floor(Math.random() * sounds.length)];\n randomSound();\n}\n",[],[242,244],"9aea5428-39cc-11f1-ae12-42b51c65c3df","sound-example.ts","9aea54c8-39cc-11f1-ae12-42b51c65c3df",["D",1776368636019],"/**\n * Example usage of the sound notification system\n * \n * In your frontend or message handler, you can call:\n * \n * import { playNotification, playSuccess, playRandom } from '../shared/sound.ts';\n * \n * // When a message arrives:\n * playNotification();\n * \n * // For success states:\n * playSuccess();\n * \n * // For random notification sounds:\n * playRandom();\n */\n\nexport const SOUND_EXAMPLES = {\n notification: \"playNotification() - high pitched beep for alerts\",\n success: \"playSuccess() - two ascending beeps\",\n random: \"playRandom() - picks one at random\",\n} as const;\n",[],[242,252],"70518c76-39cd-11f1-989c-42b51c65c3df","image-types.ts","70518cee-39cd-11f1-989c-42b51c65c3df",["D",1776368994041],"// Types for image upload feature.\n// Kept in a SEPARATE file from shared/types.ts so edits here don't conflict\n// with concurrent work on the core Message type.\n\nexport interface ChatImage {\n id: number;\n mimeType: string;\n width: number | null;\n height: number | null;\n createdAt: string; // ISO timestamp\n url: string; // public URL to fetch image bytes\n}\n\n// Upload-related constants shared between client and server.\nexport const IMAGE_UPLOAD_MAX_BYTES = 8 * 1024 * 1024; // 8 MB\nexport const IMAGE_ALLOWED_MIME_TYPES = [\n \"image/jpeg\",\n \"image/png\",\n \"image/webp\",\n \"image/heic\",\n \"image/heif\",\n] as const;\n\nexport type ImageMimeType = typeof IMAGE_ALLOWED_MIME_TYPES[number];\n",[],[242,259],"76fa8f48-39cb-11f1-ad8a-42b51c65c3df",["D",1776368146229],[202,203,204,205],[242],"705184a6-39cd-11f1-989c-42b51c65c3df","test-upload.ts","70518532-39cd-11f1-989c-42b51c65c3df","019d97d7-c6f5-75ed-bce1-84d837ece5ba",["D",1776368994041],"// Quick sanity test for the /api/images upload endpoint.\n// Run with run_file.
