Level 147

Confirm these board landmarks

Block Out Level 147 is the longest solve in the 101–150 range — a dual-chamber column shifter with a tall left `1` vault and a separate right `13` pocket. Bottom launcher pieces feed the upper grid through narrow lanes. The yellow-outlined blue column on the left must stay standing until the purple `2` tile and horizontal red bar clear the center, or the vault's feed lane collapses.
