Add a features card for native, small and offline

What changed

• public/index.html: a fifth Features card, "Native, small and offline": one small native app for Windows, macOS and Linux, built with Go; no installer, account or tracking; never connects to the internet, so samples and projects stay on the computer.
• public/style.css: .card.wide spans both columns, so the odd card sits full width under the other four instead of leaving a gap.

Notes

• Checked against the app's code: its only HTTP is Wails' in-process asset server (pad audio from Go to the window), fonts are bundled with Fontsource, and the About repo link opens in the system browser only when clicked.
• No size in megabytes: it isn't measured yet.

Testing

• Served public/ locally and checked desktop and mobile screenshots.
