The status bar now paints into NT row 1 (coin + score digits on the left, heart + lives digit on the right) using the `bg3` sub-palette that matches `sp0` pixel-for-pixel. A single OAM slot-0 anchor sprite sits over the coin tile; its one opaque pixel lines up with the coin's bottom row so sprite-0 hit fires at scanline 15, and a trailing `sprite_0_split(camera_x, 0)` latches the playfield scroll starting at scanline 16. NT rows 0-1 stay pinned while scanlines 16+ scroll with the camera. Score / lives updates are shadow-compared (`last_score`, `last_lives`) so the VRAM ring sees an entry only when the backing state actually changes — most frames append zero bytes. OAM footprint drops from 5 sprites per frame down to 1. Tile pipeline gains a 27th entry — a 7-transparent-row + 1-pixel anchor — so the sprite-0 hit lands on scanline 15 instead of scanline 8 (the latter would smear the HUD glyphs across the split). `gen_platformer_tiles.rs` is updated in lockstep. Ancillary changes: `bg3` retuned from `[yellow, orange, dk_orange]` to `[red, orange, white]` (matching `sp0`); `palette_map` row 0 flips from bg0 to bg3; legend gains `o`, `h`, `0`, `3` so the initial map can preload the static HUD tiles and the committed nametable already reads "coin 00 ... heart 3" on frame 0. `docs/future-work.md` loses the sprite-0 HUD follow-up section (this commit lands it). Goldens + gif refreshed. |
