#!/bin/bash
# ============================================================================
# setup-demo.sh  —  reset a pristine Claude Code state for demo recording.
#
# Used by `demo.tape` (vhs) so the demo runs on any fresh Linux machine:
#   * CI runners
#   * a remote server used for rendering
#   * anyone clone-and-run reproducing the GIF
#
# v0.5: we now seed projects in 3 states so the Step-1 picker shows off the
# new icon palette (🟢 active / 🔴 orphan / ❓ unknown — ⚪ empty is a rare
# edge case that's hard to construct reliably):
#   * active  — folder exists + jsonl with valid cwd + sessions ≥ 1
#   * orphan  — jsonl references a cwd whose folder is gone (primary demo
#               signal for the "I moved/deleted my project" use case)
#   * unknown — project-state directory exists but has no jsonl at all, so
#               discover_projects can't extract a cwd
#
# Running this script wipes ~/.claude/, ~/.claude.json, and the mock project
# directories under /tmp. It does NOT touch anything else.
