Subject: [PATCH] Offline packets take page 1's map from the tracked posters on
 a fresh checkout

packet.mjs looked for page 1's map sheet only in
library/scripts/posters/out/posters/, which exists only after
"bun run posters". On a fresh checkout every offline packet printed the
missing-map notice, and check:packets-all failed each fixture packet
with map=NO.

The same 28 zone poster sources are tracked in data/posters/ and ship
with the tree. The generator now looks in out/posters first (a local
run's fresh sheets win), then in data/posters. With out/posters absent,
all four fixture packets now carry their map. Messages that named the
sheet give its real path.
