# Prepare an isolated HOME for the SysWatch Lite demo recording, and print it.
#
# Why: syswatch reads its config from `dirs::config_dir()`, which is derived
# from $HOME. Recording against the operator's real config makes the GIF depend
# on whatever theme and graph style they happen to have set. Pointing HOME at a
# scratch tree makes the recording reproducible and leaves the real config
# untouched. (NetWatch learned this the hard way — a release GIF shipped in the
# wrong theme because the recording inherited the operator's config.)
#
# The theme is syswatch's own rather than the palette-deferring "terminal"
# theme NetWatch Lite records under: this GIF sits beside demo.gif in the same
# README, and the two should look like one product.
#
# `dots` + `graph_fade` is the btop-style look: braille area plots over the
# faint dot grid, with the right-bright / left-dim gradient. Both come from
# `graph::render`, which the `dots` path delegates to — `bars` in Lite stacks
# eighths itself (see `lite::draw_chart`) and so draws no grid at all.
#
# Usage (from a tape):  export HOME=$(./scripts/demo-lite-env.sh)
