# clauda installer for Windows.
#
#   irm https://clauda-install.pages.dev/install.ps1 | iex
#
# What it does:
#   1. Checks for Claude Code (`claude`). If missing, installs it with the
#      official installer: irm https://claude.ai/install.ps1 | iex
#   2. Installs clauda (clauda.cmd + clauda-impl.ps1) into
#      %LOCALAPPDATA%\Programs\clauda
#   3. Adds that folder to your user PATH so you can type `clauda`.
#
# The implementation is named clauda-impl.ps1 (not clauda.ps1) and is launched
# by clauda.cmd with -ExecutionPolicy Bypass, so `clauda` works even when the
# system PowerShell execution policy is Restricted.
#
# The clauda scripts are embedded below (base64), so this installer needs no
# other downloads.
