(&self, n: usize)

	/// Returns 0 (NUL) if past end — this maps to EOF in the CSS spec.
	#[inline(always)]
	fn peek_byte(&self, n: usize) -> u8 {
		let idx = self.pos + n;
		if idx < self.bytes.len() {
			// SAFETY: we just checked bounds
			unsafe { *self.bytes.get_unchecked(idx) }
		} else {
			0

	}

	/// Peek the next char (decoding UTF-8 if needed). Returns EOF ('\0') if at end.
