# Run this ONCE (or again whenever you swap images) on your own machine.
# It reads your two PNGs and your SOURCE script (which still has the
# empty $LogoBase64 / $HeroBase64 placeholders), bakes the images in as
# Base64 text, and writes the result to a separate BUILD file. The
# source template is never modified, so you can re-run this as many
# times as you like without worrying about state. Compile the build
# file with ps2exe whenever you're ready.
