+
+Lookup tool for Vietnam's 2016 National High School Graduation Exam (THPT Quốc gia) scores — 877,461 candidates nationwide.
+
+Fully static app running entirely in the browser (SQLite via `sql.js`). No backend, no query logging.
+
+## Features
+
+- **Quick lookup** by exam ID (`số báo danh`) or full name (diacritics-insensitive)
+- **Custom read-only SQL** (SELECT / PRAGMA / EXPLAIN / WITH) with 7 built-in preset queries
+- **Complete data**: 12 subjects (Math, Literature, Physics, Chemistry, Biology, History, Geography, English, French, German, Japanese, Chinese), exam cluster, date of birth, gender
+- Safety caps: 100 rows for lookup, 1000 rows for custom SQL
+- Dark mode, `Ctrl+Enter` shortcut to run queries
+
+## Demo
+
+<https://tiennm99.github.io/thptqg/2016/>
+
+## Development
+
+```bash
+# Build the SQLite database from source Excel files (requires Rust stable)
+pnpm run build:db
+
+# Or build in two steps:
+pnpm run build:rust          # compile the xlsxread binary
+./tools/xlsxread/target/release/xlsxread build \
+  --schema tools/xlsxread/configs/thptqg2016-data.toml \
+  --input data \
+  --output public/thptqg2016.db
+
+pnpm run dev         # Vite dev server
+pnpm run build       # Production bundle → dist/
+pnpm run lint        # ESLint
+```
+
+The database is built by the `xlsxread` Rust binary (`tools/xlsxread/`), which
+reads the 119 mixed `.xls`/`.xlsx` files and auto-detects the column layout per
+file (`separate-scores`, `mapped`, or positional default). No Node.js Excel
+library is required at build time.
+
+The GitHub Actions workflow (`.github/workflows/deploy.yml`) compiles
+`xlsxread`, builds the DB, gzips it, and deploys to GitHub Pages on every push
+to `main`.
