The "Add OPDS Catalog" dialog (a ModalPortal opened from inside Settings > Integrations > OPDS Catalogs) rendered behind the Settings sheet on mobile, so the form could not be reached or filled in. Root cause: PR #3235 raised the Settings dialog to z-[10050] to clear the full-screen RSVP overlay (z-[10000]) for in-overlay dictionary management. That also jumped Settings above the ModalPortal layer (z-[100]), so any modal opened from inside Settings was buried. The bug is mobile-only because on desktop the rounded-window frame (.window-border, z-99) traps the inline-rendered Settings dialog in its own stacking context, while ModalPortal escapes to document.body and wins there. Redesign the overlay z-index into a compact scale (no four-digit values), each layer clearing the z-99 page frame: 100 RSVP overlay 101 RSVP controls (start dialog, lookup chip) 110 Settings dialog 120 modal / command palette 130 toast / alert 200 app lock Lock the ordering with a static test that reads the values from source and would have caught the #3235 regression. Documented in DESIGN.md. Verified on a Xiaomi device via CDP: elementFromPoint at the dialog center now resolves inside the Add Catalog form instead of Settings.
