/* adiverse polish layer
   Shared interaction + motion layer, loaded on every page after the page's own <style>.
   Principles (Apple "Designing Fluid Interfaces"):
   - feedback on press, not release
   - motion that settles like a critically damped spring, no lingering ease-in
   - enter and exit along the same path
   - restraint: nothing loops forever to grab attention
   - reduced motion / transparency / contrast are respected everywhere */
