  1) full      - everything. Voice (Whisper+sounddevice), browser tools (Playwright),
                 MemPalace semantic memory, tmux. Heaviest install. ~1.5 GB.
                 Best for daily-driver setups.

  2) standard  - REPL + webchat + tmux daemon + Telegram bridge.
                 Skips voice, browser automation, semantic memory.
                 ~300 MB. The "I just want to chat" sweet spot.

  3) basic     - bare pip install dulus. No system deps installed.
                 ~150 MB. For minimal sandboxes / scripted environments.

  4) custom    - toggle each feature one by one.

  Get going:
    dulus                    open the REPL
    dulus --help             list flags
    dulus -c "help"          list every slash command
    dulus -c "bg start"      run headless daemon in tmux + webchat

  First-run picks:
    * Pick a model with /model (NVIDIA tier is free - 14 frontier models)
    * Set your soul with /soul (English / Spanish / your own)
    * /help inside the REPL shows everything

  Trouble?
    dulus -c "doctor"        run the full health check
