📝 Walkthrough

Walkthrough

The demo tape (docs/demo.tape) is updated to use a throwaway HOME under /tmp/pythonlings-demo and launch pythonlings directly without an explicit init step. docs/DEMO_GIF.md is updated to match, rewriting the numbered workflow to start with the zero-setup first run.

Changes

Demo zero-setup first-run flow

Layer / File(s)	Summary
Tape: disposable HOME, launch, and TUI navigation docs/demo.tape	Adds a hidden pre-step creating /tmp/pythonlings-demo as a throwaway HOME, removes the prior explicit init/cd flow, launches pythonlings directly to open the first exercise, and adjusts keystroke ordering and Sleep timings for TUI navigation and the CLI segment.
DEMO_GIF.md: updated workflow steps docs/DEMO_GIF.md	Rewrites the "What the Demo Shows" numbered list to begin with running pythonlings with no prior setup, matching the updated tape sequence.

Poem

🐇 Hop into the demo, no setup required,
A fresh /tmp home is all that's desired.
pythonlings runs from a clean little den,
No init, no fuss — just code once again!
The tape and the docs now dance in one line,
First-run flows freely, like rain and sunshine. ✨
