Calculator — Windows 11 replica
===============================
  Version 1.1.0

HOW TO RUN
  Keep Calculator.exe and resources.neu together in the same folder,
  then double-click Calculator.exe. Nothing is installed and nothing is
  written to the registry; delete the folder to remove it.

  Pin it: right-click Calculator.exe > Pin to Start, or make a desktop
  shortcut. The shortcut may live anywhere, but the two files must stay
  side by side.

REQUIREMENTS
  Windows 10 1809 or later, 64-bit. Uses the Microsoft Edge WebView2
  runtime, which ships with Windows 11 and with current Windows 10.
  If the window does not appear, install "Microsoft Edge WebView2
  Runtime (Evergreen Standalone Installer, x64)" from microsoft.com.

  Unsigned build: SmartScreen may show "Windows protected your PC" on
  first launch. Choose More info > Run anyway.

UPDATES
  The app checks https://kreayotoo-calculator.pages.dev on launch and
  offers an update when one is published. "Update and restart"
  downloads only resources.neu (about 170 KB) and restarts — the .exe
  itself is not replaced, so you never re-copy the folder. Menu >
  Check for updates runs the check on demand. Offline machines fail
  the check silently and carry on.

NOTES
  The window is borderless, so the title bar inside the app is the real
  one: drag it to move, and use the grip at the bottom-right corner to
  resize. Each mode sizes the window to fit itself.

  Currency rates are offline reference values. Edit the rate field to
  match the day's market.

  This is a clean-room rebuild of the Windows Calculator's features and
  layout. No Microsoft code, assets or fonts are included, and it is not
  affiliated with or endorsed by Microsoft.
