wire up Crystal PalMap tile attrs (bank 1, flips, BG_PRIO) through map bake,
attr grid, and BG-over-OAM blits instead of the gold/silver grassAtlasFor shortcut.
crystal-only: MapAttrGrid + TileAttrs, OAM bottom/top split for IN_GRASS,
keyed grass over feet strip via attrmap, drawBgPriorityOver for wAttrmap bit 7.
gold/silver left alone on the old path — all of this gated behind isCrystal().
fixes standing still in grass with tufts on torso / feet on top of grass (#2080).
RomExtractorGen2 pulls crystal PalMap attrs; SpriteRenderer splits standing
sheets on frameHeight; tests for tile attrs + feet strip regression.
