Lemonade Stand: browser recreation of the Atari 8-bit BASIC game

Faithful day loop - weather report, cost of lemonade rising over the
summer, glasses/signs/price decisions, thunderstorms, heat waves and
street crews - with the $$ LEMONSVILLE DAILY FINANCIAL REPORT $$ laid
out the way it printed.

The simulation is kept out of React so a season can be run headlessly:
a careful player compounds $2.00 into roughly $22 over twelve days,
while an all-in player goes broke about seven times in ten.

Weather scenes are pixel rectangles in SVG and the music is a small
chiptune engine on the Web Audio API, so there are no binary assets.
The screen is locked to a 4:3 tube and never scrolls.
