// Hello Sprite — the simplest NEScript program.
//
// Displays a sprite on screen and moves it with the d-pad.
// Build:  cargo run -- build examples/hello_sprite.ne
// Output: examples/hello_sprite.nes (open in any NES emulator)
//
// Note: In M1 the sprite name in `draw` is parsed but not resolved.
// All sprites use tile 0 from the built-in CHR data (a smiley face).
// Sprite declarations with custom tile data come in M3.
