Detailed Description

Static helpers that build Game Boy tileset graphics (tiles, flowers, waves).

The rendering workhorse behind TilesetProvider and the font previews: it loads a named tileset image, slices it into per-tile pixmaps, overlays animated flowers and the font, and applies the animated water "wave" post-process. All static; the constexpr values are the GB tile geometry. The id-string format for buildTileset() is documented inline.
