The one shift: what you ship is not "a correct program" but a maintained ILLUSION of direct manipulation over a real, asynchronous, failing system — so loading / error / empty / edge states aren't afterthoughts, they ARE the product, and accessibility and a performance budget are built in from the first slice, not bolted on. Triggers on "build this component / feature", "loading / error / empty states", "optimistic update", "skeleton screen", "animation / transition", "accessibility / a11y / keyboard / screen reader / focus", "performance / Web Vitals / INP / LCP / CLS / bundle size", "it feels janky / slow", "race condition / stale response".
