With five cells per row, we’ll need to dedicate five sprites to the cells’ drop shadows. We will reuse those cells in each subsequent row, and if a shadow needs to go missing (because the corresponding button is depressed), we will simply disable that sprite on that row via the $D015 register. Two sprites will suffice for the corner sprites; the top corners may be similarly re-used for the bottom ones. That leaves one sprite spare, and it seems like it would be most conveniently used for the rest of the left-side shadow.

Web streams has no synchronous path. Even if your source has data ready and your transform is a pure function, you still pay for promise creation and microtask scheduling on every operation. Promises are fantastic for cases in which waiting is actually necessary, but they aren't always necessary. The new API lets you stay in sync-land when that's what you need.
