Demo a style whose effect is actually visible

The templates loaded a documentary photography style that compiles to
"photography, naturalistic lighting, deep focus, RAW-like" — close to what
SDXL produces unprompted — so the first queue looked like the nodes had done
nothing, and the demo subjects were unrelated scenery on top of that.

Load Renaissance Mythic Classicism instead: tempera-on-panel technique and a
muted Renaissance palette, unmistakable against a base render, with no
typography for the sampler to turn into gibberish and no subject it rules
out. Subjects are now concrete everyday scenes carrying no style words of
their own.
