Pull request overview
This PR tightens the mobile/tablet sidebar “closed” state so the off-canvas drawer can’t remain visually present (or stack incorrectly) due to later desktop sidebar rules in main.css.
Changes:
- Forces the mobile/tablet sidebar closed state to use
transform: translateX(-100%) !importantandvisibility: hiddenwith a delayed visibility transition. - Ensures the opened sidebar becomes
visibility: visibleand keeps its stacking above the overlay viaz-index: 999 !important.
