Output gains a number input `alpha`; unconnected it reads the texel's alpha, like `color` reads the texel. The epilogue premultiplies with the resolved alpha. New `Texture alpha` node exposes texel.a for maths. PortDef.inline=false keeps the alpha port without an inline field: every number port is inline by default, and a typed default of 0 would have made every shaded sprite invisible. The compiler's texel fallback is typed: colour ports get rgb, number ports get texel.a. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
