/*
 * pagedrop UI, Apple-style.
 * Principles (apple-design / emil-design-eng): system type with size-specific tracking, light + dark that follow
 * the system, translucent chrome that content scrolls under, feedback on press, enter/exit that grow from where
 * they came, short ease-out motion (< 300 ms), and gentler equivalents for reduced motion / transparency.
 * Every :hover lives behind (hover: hover) so taps never leave a stuck hover state.
