This is a Next.js project bootstrapped with create-next-app.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.js. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Inter, a custom Google Font.

Deploy on Vercel

The easiest way to deploy your Next.js app is to use the Vercel Platform from the creators of Next.js.

Mobile responsiveness

This app supports small screens (320–430px) while keeping the desktop layout unchanged.

• Layout stacks vertically on mobile and preserves horizontal layout on md+.
• Buttons/inputs are full-width on small screens for easier tapping.
• A bottom padding is added to avoid the fixed footer overlapping content.
• The bomb image scales with viewport width; the timer overlay uses percentage positioning on mobile.

Testing tips:

1. Start the dev server and open the app.
2. Use DevTools device emulation (iPhone SE/12/14 Pro) to verify there is no horizontal scrolling.
3. Try presets, adjust volume, and confirm controls are reachable and legible.
