ludic.base: a queue's fact records come round again (q_rec / q_ring_add), used by effects, clock, wallet, weather, tracks, needs, fire, settings, update, steps, crafting, shop, gear, hints, session and photo instead of a new record per fact; the minimap's marks cleared and rubbed out in place, its scale steps without a list; the clock's dice seeded again, not made again; once-per-join, per-save and pool-miss paths declared

+# ludic.base/queue_ring.ludic - a fact's record made again rather than new: Ludic frees nothing, and a
+# mechanic reports all day. q_rec hands out a record neither waiting in the queue nor handed out by
+# its last drain, or null when every one is: the caller makes one more and q_ring_add keeps it, so
+# the ring grows to the busiest frame and stays there. The caller sets every field it reads
