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.
