Summary

bookmarking and native sharing for tablets and highlights, plus the Saved tab

Bookmarks

Zustand store persisted to MMKV -> survives restarts, no backend or accounts needed
Two separate id lists (tablets, highlights) rather than one tagged list; highlight ids (185–214) fall inside the tablet range (29–782), so a single list would confuse tablet 187 with highlight 187
Header bookmark icon on both detail screens; Ionicons filled/outline pair for saved state
Saved tab - one FlashList over a flattened row union so section headings keep virtualisation; ids resolve against the cached feeds, nothing duplicated into storage. A heading only shows when that list has items

Share

Built-in RN Share API, no dependency
Tablets share title (theme) + https://cdli.earth/cdli-tablet/{id}
Highlights share title + https://cdli.earth/postings/{id}
URL goes inside message, not the separate url field -> url is iOS-only and Android drops it silently
"View on CDLI" now opens the same page the share link points to
