/* Loopcut — built on Apple's interface principles (WWDC "Designing Fluid Interfaces", "Details of UI Typography"):
   system type with size-specific tracking, colours that follow light/dark, a translucent nav with a scroll-edge
   effect instead of a hard rule, press feedback on pointer-down, critically damped motion (no overshoot), and the
   reduced-motion / reduced-transparency / increased-contrast preferences honoured. */
