# lib/output.ps1 - output helpers, mode colours, the banner and usage.

# Part of claude-mode.ps1, which dot-sources it into its own script scope after
# the settings at its top. Not meant to run on its own. ASCII only: Windows
# PowerShell 5.1 reads a .ps1 without a BOM as ANSI. $PSScriptRoot here would be
# lib\, so paths beside the main script go through $script:Here.
