Animated Tooltips
Three opinionated tooltip animations — a frosted-glass command-palette tip with a purple-pink-blue gradient halo + ⌘K keycap (spring scale-in), a rich profile-preview card that unfurls on @-mention hover with a pulsing online dot and italic stats (-1.8° rotate-in), and an editorial marginalia footnote that draws a dotted connector down to a tilted parchment aside with an asterism ornament. Each one uses :hover + :focus-within so keyboard users get the same affordance.
