Find, summarize, and curate developer resources from the Cardano.Build index (https://cardano.build/). Use this when the user asks for Cardano developer starting points, tools, libraries, tutorials, SSI/identity, infrastructure, APIs, or “where do I start” type guidance. Focus on build-related material (not price/markets). Produce concise, categorized results with links and short rationales. Prefer official docs and recent, maintained resources.
