Made a story-driven construction-truck coloring book for my nephew — figured other truck-obsessed kids might like it too

He's 5 and obsessed with diggers and dump trucks, so I put together a coloring book where the trucks actually go on a mission together instead of just being random pictures to color. Ended up turning it into a real project (Bolt, Crusher, Sky and Blaze — ages 4-8, single-sided pages so markers don't bleed through). Sharing here in case anyone else has a truck-loving kid and wants to check it out — happy to answer questions about how I put it together too.
