Fixed
- Scrolling on mobile Safari (iOS 26+) and narrow-viewport browsers no longer causes the entire page to go blank. Root cause:
backdrop-filteronposition:stickyelements inside anoverflow:autoscroll container triggers a WebKit compositor bug that blanks the whole scroll container. Fixed by removingbackdrop-filterfrom all sticky toolbars (Tasks, Notes, Contacts, Calendar, Housekeeping, Shopping list headers) and.sticky-header, replacing semi-transparent glass backgrounds with an opaquevar(--color-bg).
