Optimized for mobile + desktop.\n\n## Architecture\n\n```mermaid\ngraph LR\n Browser -->|\"GET /\"| Hono[\"index.ts (Hono)\"]\n Hono -->|serves| HTML[\"frontend/index.html\"]\n HTML -->|loads| Entry[\"frontend/index.tsx\"]\n Entry -->|renders| App[\"components/App.tsx\"]\n App -->|useMessages| Hook[\"hooks/useMessages.ts\"]\n Hook -->|\"GET /api/messages (initial load)\"| API[\"index.ts API routes\"]\n Hook -->|\"POST /api/messages (send)\"| API\n Hook -->|\"GET /api/stream (SSE, long-lived)\"| API\n API -->|read / write| DB[(\"SQLite
messages_v1\")]\n API -->|\"SSE: id, event, data\"| Hook\n```\n\n## How realtime works\n\n- Client opens **one** SSE connection to `GET /api/stream?sinceId=N`.\n- Server polls SQLite every ~1.5s for rows with `id > lastSent` and pushes\n each new row as an SSE `message` event (with the row id as the event id).\n- Server closes the stream after 5 minutes; the browser's `EventSource`\n automatically reconnects and resumes from `Last-Event-ID`. This keeps\n individual isolates from piling up while preserving delivery semantics.\n- Heartbeat comments are sent every 20s so intermediaries don't drop idle\n connections.\n- POSTing a message only inserts into SQLite — the SSE stream delivers it,\n so there's a single source of truth and no dedup logic needed on the client.\n\n## File structure\n\n```\nindex.ts ← Hono server + /api routes + SSE stream\ndatabase/db.ts ← SQLite schema + queries\nshared/types.ts ← Message type shared by client & server\nfrontend/\n index.html ← Shell (full-height, viewport-fit=cover for mobile)\n index.tsx ← React entrypoint\n components/\n App.tsx ← Layout + status dot\n MessageList.tsx ← Renders messages (no auto-scroll)\n MessageInput.tsx ← Input + Send (no auto-focus)\n hooks/\n useMessages.ts ← Initial load + SSE subscription + send\n```\n\n## Design choices\n\n- **No auto-scroll**, **no auto-focus** on the input — per spec.\n- **Mobile friendly**: `100dvh` layout, `font-size: 16px` on input to prevent\n iOS zoom-on-focus, `overscroll-behavior: none` on body.\n- **Rounded pill send button** with disabled state when the input is empty.\n- Messages never delete; `messages_v1` table is append-only.\n",[168],"3e5cf4a4-39cc-11f1-8e94-42b51c65c3df","shared","019d97cf-f1d3-767a-8e7a-a44d1988cafd",["D",1776368480732],[174],"3e5cf17a-39cc-11f1-8e94-42b51c65c3df","frontend","019d97cf-f1d3-767a-8e7a-9f8347a84e4d",["D",1776368480732],[179],"3e5c2542-39cc-11f1-8e94-42b51c65c3df","database","019d97cf-f1d3-767a-8e7a-6eb264e5db1b",["D",1776368480732],[184],"585957bc-39cc-11f1-ac05-42b51c65c3df",["D",1776368524338],[34],"pulls","branches",3,"forks","envVars",{"_199":74,"_201":74},"connections",{"_199":74,"_200":74},"count","unfilledCount","emptyCount",{"_54":188,"_38":34,"_36":37,"_159":-5,"_45":46,"_44":14,"_161":70,"_42":347,"_13":74,"_39":40,"_41":-5,"_30":31,"_165":-5,"_225":348,"_33":349},{"_54":343,"_38":50,"_36":49,"_159":37,"_45":46,"_44":14,"_161":70,"_42":344,"_13":74,"_39":51,"_41":52,"_30":31,"_165":-5,"_225":345,"_33":346},{"_54":183,"_38":184,"_36":185,"_159":-5,"_45":46,"_44":160,"_161":70,"_42":340,"_13":74,"_39":40,"_41":-5,"_30":31,"_165":-5,"_225":341,"_33":342},{"_54":333,"_38":334,"_36":335,"_159":185,"_45":46,"_44":160,"_161":70,"_42":336,"_13":74,"_39":51,"_41":337,"_30":31,"_165":-5,"_225":338,"_33":339},{"_54":327,"_38":50,"_36":328,"_159":185,"_45":46,"_44":193,"_161":70,"_42":329,"_13":74,"_39":51,"_41":330,"_30":31,"_165":-5,"_225":331,"_33":332},{"_54":178,"_38":179,"_36":180,"_159":-5,"_45":46,"_44":160,"_161":70,"_42":324,"_13":74,"_39":40,"_41":-5,"_30":31,"_165":-5,"_225":325,"_33":326},{"_54":320,"_38":291,"_36":286,"_159":180,"_45":46,"_44":160,"_161":70,"_42":321,"_13":74,"_39":40,"_41":-5,"_30":31,"_165":-5,"_225":322,"_33":323},{"_54":313,"_38":314,"_36":315,"_159":286,"_45":46,"_44":160,"_161":31,"_42":316,"_13":74,"_39":51,"_41":317,"_30":31,"_165":-5,"_225":318,"_33":319},{"_54":306,"_38":307,"_36":308,"_159":286,"_45":46,"_44":160,"_161":70,"_42":309,"_13":74,"_39":51,"_41":310,"_30":31,"_165":-5,"_225":311,"_33":312},{"_54":299,"_38":300,"_36":301,"_159":286,"_45":46,"_44":160,"_161":70,"_42":302,"_13":74,"_39":51,"_41":303,"_30":31,"_165":-5,"_225":304,"_33":305},{"_54":292,"_38":293,"_36":294,"_159":286,"_45":46,"_44":160,"_161":70,"_42":295,"_13":74,"_39":51,"_41":296,"_30":31,"_165":-5,"_225":297,"_33":298},{"_54":283,"_38":284,"_36":285,"_159":286,"_45":46,"_44":160,"_161":31,"_42":287,"_13":74,"_39":51,"_41":288,"_30":31,"_165":-5,"_225":289,"_33":290},{"_54":279,"_38":278,"_36":273,"_159":180,"_45":46,"_44":160,"_161":70,"_42":280,"_13":74,"_39":40,"_41":-5,"_30":31,"_165":-5,"_225":281,"_33":282},{"_54":270,"_38":271,"_36":272,"_159":273,"_45":46,"_44":160,"_161":70,"_42":274,"_13":74,"_39":51,"_41":275,"_30":31,"_165":-5,"_225":276,"_33":277},{"_54":263,"_38":264,"_36":265,"_159":180,"_45":46,"_44":160,"_161":70,"_42":266,"_13":74,"_39":27,"_41":267,"_30":31,"_165":-5,"_225":268,"_33":269},{"_54":256,"_38":257,"_36":258,"_159":180,"_45":46,"_44":160,"_161":31,"_42":259,"_13":74,"_39":27,"_41":260,"_30":31,"_165":-5,"_225":261,"_33":262},{"_54":249,"_38":250,"_36":251,"_159":180,"_45":46,"_44":160,"_161":70,"_42":252,"_13":74,"_39":51,"_41":253,"_30":31,"_165":-5,"_225":254,"_33":255},{"_54":173,"_38":174,"_36":175,"_159":-5,"_45":46,"_44":160,"_161":70,"_42":246,"_13":74,"_39":40,"_41":-5,"_30":31,"_165":-5,"_225":247,"_33":248},{"_54":238,"_38":239,"_36":240,"_159":175,"_45":46,"_44":241,"_161":70,"_42":242,"_13":74,"_39":51,"_41":243,"_30":31,"_165":-5,"_225":244,"_33":245},{"_54":231,"_38":232,"_36":233,"_159":175,"_45":46,"_44":160,"_161":70,"_42":234,"_13":74,"_39":51,"_41":235,"_30":31,"_165":-5,"_225":236,"_33":237},{"_54":167,"_38":168,"_36":169,"_159":-5,"_45":46,"_44":160,"_161":70,"_42":228,"_13":74,"_39":27,"_41":171,"_30":31,"_165":-5,"_225":229,"_33":230},{"_54":156,"_38":157,"_36":158,"_159":-5,"_45":46,"_44":160,"_161":31,"_42":224,"_13":74,"_39":163,"_41":164,"_30":31,"_165":-5,"_225":226,"_33":227},["D",1776368480732],"children",[],[157],["D",1776368480732],[],[168],"3e5cf2ce-39cc-11f1-8e94-42b51c65c3df","types.ts","019d97cf-f1d3-767a-8e7a-a10854c10570",["D",1776368480732],"export interface Message {\n id: number;\n text: string;\n createdAt: string;
