## Architecture Notes
|
|
|
|
- **Domain**: Simple Calculator — arithmetic operations (add, subtract, multiply, divide at minimum).
|
|
- **Stack**: Plain HTML/CSS/JS — no framework or build step.
|
|
- `index.html` contains the full UI structure: operand inputs, operation buttons, calculate/clear buttons, result `<output>`, and an error `<p role="alert">`.
|
|
|
|
## Code Style
|
|
|
|
No linter or formatter has been configured yet. Update this section once tooling is set up.
