+<#
+.SYNOPSIS
+    Installs ctop (container terminal UI) from GitHub releases.
+
+.DESCRIPTION
+    Auto-detects the latest release from
+    https://github.com/bcicen/ctop/releases, downloads the binary
+    matching your Windows architecture, and installs it.
+
+    Supported architectures:
+      - x64  (AMD64 / Intel 64bit)
+
+    NOTE: ctop only provides a windows-amd64 binary. ARM64 is not supported.
+
+.PARAMETER InstallDir
+    Directory to install ctop.exe. Default: $env:USERPROFILE\.local\bin
+
+.PARAMETER AddToPath
+    Whether to permanently add InstallDir to user PATH. Default: $true
+
+.EXAMPLE
+    .\install-ctop.ps1
+    .\install-ctop.ps1 -InstallDir "C:\tools\bin"
+    .\install-ctop.ps1 -AddToPath $false
+
+    # One-liner install from remote (download then run; -ExecutionPolicy Bypass for current process only):
