I would assume that all of the reading system's app resources would be
cached "immediately" (i.e. as early as possible in the bootstrap
process), so that the reading system itself is available offline.
However, publication content would be cached according to a particular
strategy (on-demand vs. preload, LRU eviction, etc.), in terms of
offline-ing multiple publications, but also in terms of offline-ing
resources within a given publication (partial fetch vs. full cache).
