The reader's question is answered entirely by data already on the device and
countdowns run off the local clock, so losing signal should not lose the app.
The shell is cache-first; the feed is network-first falling back to the last
copy seen, because stale events beat a blank screen. Webfonts are cached too
— without them an offline load silently drops to system faces and the whole
thing changes character.
Offline is surfaced in the header and above the footer rather than hidden:
stale data must never be presented as current.
