On desktop the app runs multiple windows (one library plus one per open
book), and each keeps its own in-memory settings loaded once at window
open. Global settings persist to a single shared settings.json, and every
window writes the whole object on save. A window opened before the user
customized a global view setting therefore clobbers that change with its
own stale (often default) value on its next save, most visibly a reader
window reverting Click to Paginate back to the default on close.
Broadcast the global view and read settings after every save and have all
other windows adopt them, preserving each window's device-local fields
(paths, lastOpenBooks, sync cursors, brightness). The receive path only
updates the in-memory store, so there is no save or broadcast loop. No-op
off Tauri.
