# Builds the synthetic fleet the dashboard recording is made against.
# Everything on screen is REAL: real repositories, real shims written by the
# real release binaries, scanned by the real dashboard — only the repositories
# are small and named for a story. Nothing is re-enacted or edited afterwards,
# same rule as demo.sh.
#
# To re-record (needs `asciinema`, `agg`, and the `expect` every macOS ships):
#
#     cargo build --release --bin amont --bin amont-fleet
#     sh docs/assets/fleet-demo.sh                # builds /tmp/fleet-root
#     HOME=/tmp/fleet-home XDG_CONFIG_HOME=/tmp/fleet-home/.config \
#     GIT_CONFIG_GLOBAL=/tmp/fleet-home/.gitconfig GIT_CONFIG_SYSTEM=/dev/null \
#         asciinema rec --overwrite --cols 96 --rows 30 \
#         --command "expect docs/assets/fleet-demo.exp" \
#         docs/assets/fleet-demo.cast
#     agg --theme monokai --font-size 15 --idle-time-limit 2 \
#         docs/assets/fleet-demo.cast docs/assets/fleet-demo.gif
#
# The isolated HOME/GIT_CONFIG_* is the same argument as demo.sh: without it
# the recording publishes the recorder's own directory layout and global git
# config to strangers.
#
# expect stands in for the keyboard because a TUI cannot be driven from a
# pipe: it allocates the pty, sends the keystrokes on a schedule, and passes
# the frames through to asciinema untouched.
