/* ============================================================
   LEVEL JOINERY — motion layer
   GSAP ScrollTrigger drives .reveal / .reveal-stagger via JS
   (adding/removing .is-visible). This file defines the states
   only — timing/easing lives in the GSAP calls in each page's
   inline <script>, per the "considered, unhurried" brief:
   power2/power3/power4 easing only, never elastic or bounce.
