/* Paper Director v1.2.27 · Apple-inspired UI boundary system
   -----------------------------------------------------------
   Design goals:
   1) one scrolling owner per region; no nested accidental page scroll
   2) every grid/flex child can shrink (min-width/min-height:0)
   3) calm surfaces, thin separators, restrained shadows
   4) controls share one size/radius/focus language
   5) responsive behavior changes layout instead of squeezing content
