- Show skeleton in PublicNoteView and StackedPublicNote while note
content is pending author resolution
- Show skeleton h1 in PublicNoteListByDidView while author loads
- Show skeleton in SignInAtproto until auth state is known
- Load cached session from IndexedDB before OAuth restore so the
homepage resolves immediately without waiting for network
- Pass didrkey (with colons) instead of classNameId to scrollToFocusedNote in StackedPublicNote, so findIndex matches the URL-stored ID
- Revert includes() to strict === in findIndex for semantic correctness
