# Shoots the theme gallery in the README: the Split view once per color
# preset, each on a terminal wearing the matching palette, plus the
# borderless example. Run
# `./gallery.sh` from the repo root after `cargo build --release`, with an
# AlphAI key configured and vhs installed.
#
# A vhs tape sets its terminal theme once, so this writes one small tape
# per preset and runs them in turn. Every take is a launch of the app, so
# the whole gallery costs ten price requests per ticker: the ticker list
# is short on purpose, and the takes are spaced out, because Yahoo blocks
# an address after about ten quick requests. Point YAHOO_CHART_URL at a
# caching proxy to pay for each request once.
#
# The takes read a throwaway config holding nothing but the AlphAI key: a
# watchlist and holdings are private, and these images are published. The
# last take is the borderless example (`[ui] borders = "none"`), passed as
# a flag-free config line of its own.
