How do we make web accessibility doable for devs with zero a11y budget?

Most of us don’t work at companies that can afford dedicated accessibility teams or weeks of audits. We still want the app/blog/tool we ship to be readable by actual humans, but opening WCAG feels like drowning. Big companies build their own ships across the accessibility ocean. The rest of us are standing on the shore with a hammer and some planks. What tools, checks, or one-line fixes would actually let you cross that gap without derailing your weekend project?
