stringadmin e555209516 fix: page transition UI jitter — remove enter phase to prevent double animation
The three-phase exit→enter→idle flow caused a visible "double refresh"
jitter. During the enter phase (220ms), the wrapper animated from
opacity:0 while cancelling child .page-motion with animation:none
!important. When phase switched to idle, the !important rule was
removed and child .page-motion re-triggered, creating a second
entrance animation — the jitter.

Fix: remove the enter phase entirely. After exit animation (180ms),
phase goes directly to idle. The child page's own .page-motion class
handles entrance naturally via React's fresh DOM mount. No wrapper
animation on enter, no double-animation conflict.
