- Bug 2: raise all FABs (activity, memories, circle) to z-50 and bottom-24
so they sit above the bottom nav (z-40, ~56px tall)
- Bug 1: add onError handlers to baby photo (home) and parent avatar (profile)
so a broken R2 URL shows the 👶 / initials placeholder instead of a broken
browser icon; reset error flag after a successful upload
- Bug 3: replace ⏳ emoji spinner with a proper CSS spinner on home page baby
photo; add a fixed upload-progress toast to the memories page that appears
at the top of the screen for the full duration of the upload
