# _board.py — draw a SCOREBOARD PLATE. One frame, full-bleed, no figures.
#
#   python3 assets/_board.py match      # the zombie-tennis board -> assets/scoreboard_z.png
#
# _regen.py cannot do this job: it keys a magenta background, crops to ink and rescales every figure
# to a common 224 height, and a scoreboard is a full-bleed RECTANGLE with no figure in it. So this
# is the same generate-and-install loop with the sprite machinery taken out — generate, resize to
# the exact plate size the HUD draws (render.js draws it at 150x42 from a 300x84 source), quantise
# to flat pixel-art colours, install.
#
# It is deliberately a plate and NOT a tint of the club's board: the two boards say different things
# and one of them is the club's, so the second is drawn rather than filtered (see the settled rule —
# procedural is for blood, fire and smoke, not for art).
