Shared Mario runtime artwork

Nintendo artwork and game audio remain separate from software licenses. No public
or commercial redistribution permission for Nintendo or Contra assets is granted
by this package. Some source-pixel data is reconstructed or adapted; availability
of source code does not make the original character art open-licensed.

The Shoe Goomba and Koopa Clown Car data retain decoded static pixels; historical
source hashes identify historical source responses rather than new reconstructed
PNG files. One static Clown Car frame is reused with authored seating/compositing.

Springboard standing pixels are from the SMM SMB1 source below. Compression is an
authored adaptation, not a recovered original compressed animation.

SMM1/SMM2 sprites, SMW motion data and authored SMB3 approximations may coexist in
the shared renderer. Their embedded source records retain per-resource identities;
an adapted animation must not be described as an exact original-game animation.
Font terms are retained in CHILL_FONT_LICENSE.txt.
