Scope
Adds
scripts/validate_player_sheets.py, a Pillow-based validator for the indexed player sprite sheets specified in #140.Checks palette order against
ntba.gpl, indexed PNG mode, palette index 255 transparency, legal indices, frame dimensions and transparent margins, manifest frame/origin/clip contract and role ramps.Status
Draft / partial implementation. The actual hand-authored replacement sprite art is not included yet; existing placeholder PNGs remain unchanged. The issue's former reference branch is no longer present, but the palette, manifests and placeholders are now on main.
Run
python3 -m pip install Pillow && python3 scripts/validate_player_sheets.pyCloses no issue; groundwork for #140.
