Component Libraries
Copy-paste and installable UI component sets — the shadcn registry ecosystem, React libraries, headless primitives, and the odd native or cross-framework kit.
For an agent. Look here first when you must write actual interface code and want a real component (button, table, combobox, editor, map, upload) instead of inventing markup.
