# SocialLive installer for Windows 10/11

# Provisions a user-local Node.js + FFmpeg runtime (no admin rights needed),
# downloads and builds SocialLive into %USERPROFILE%\.social-live, registers a
# Scheduled Task so the dashboard starts with Windows, and opens the browser.

# Flags:  -Uninstall   -Port 3000   -Dir "C:\path"   -NoService   -Update

# ══ AxionInstaller v1 (auto-embedded — edit AxionInstaller/lib instead) ══
# ══════════════════════════════════════════════════════════════════
#  AxionInstaller — PowerShell UI library      v1.0 · AxionAura
#  Branded terminal UI for Windows installers (Windows 10/11).
#  Design tokens: indigo #6366f1 · violet #8b5cf6 · purple #a855f7 ·
#  fuchsia #d946ef · bg #06090f · fg #e6edf3 · muted #8b949e
#
#  Public API:
#    Initialize-Axion <Project Name> [Tagline]
#    Invoke-AxionStep -Label "..." -Script { ... }   (atom spinner)
#    Write-AxionInfo / Ok / Warn / Fail "msg"
#    Write-AxionBanner
#    Complete-Axion -Lines "a","b"
#  Rules:
#    • Call Initialize-Axion first. Non-interactive hosts fall back
#      to plain logs automatically (CI safe).
