# It seeds a scripted player's history first: the honest first-run screens are all dashes and empty
# states, which is right for a person and useless as an advertisement.
#
# Six screens are opened by name through POKERTUTOR_SCREEN. The other two — the felt with a
# decision on it, and the coach's review — need a game behind them, so they are asked for as scenes
# through POKERTUTOR_DEMO: the app plays a fixed-seed game against itself until the scene is on the
# table (see Sources/PokerUI/Demo.swift). A test plays both scenes headlessly, for both products,
# so a seed that stops producing them fails the suite before it produces a blank felt here.
#
# Two products come out of this project — Poker Tutor (tournaments) and Poker Tutor Cash — and
# each has its own scheme, bundle id, history folder and set of shots. The product is the first
# argument; the cash product's felt is shot at a 50/100 fixed-limit table and its review at a
# 50/100 no-limit one.
