Screenshot capture animation: a toast counts "Capturing selection…" up to 100% over a browser window, the window drops away and shrinks, the toast pops to "Copied to clipboard." and a two-line headline rises out from behind the window while the cursor glides up. Every curve was measured off a recording frame by frame: the window's drop and shrink share one cubic-bezier, the toast pops on another, the headline rises without scaling or blurring, and type moves by fractions of a pixel.
