- assets/board/background.png: full-screen 863x1822 RGB gradient (opaque,
exact 9:19), re-encoded from the provided source.
- assets/board/cell.png: 128x128 RGBA rounded glass tile. The painted
gray/white transparency checkerboard is keyed to real alpha via an
8-connected flood fill from the border, using a low-saturation predicate
(checker spread<=12, panel is bluish spread>=20) so the rounded panel is
preserved; the clean RGBA is then downscaled 1254->128 with LANCZOS.
- assets/fonts/default.ttf: Lato Regular, SIL Open Font License 1.1
(tyPoland Lukasz Dziedzic, Reserved Font Name "Lato"); OFL.txt shipped
alongside per the license.
All three bundle into the ios-sim M3te.app build and decode cleanly.
