Go to Declaration and Cmd-click said "Cannot find declaration" on HTML href/src, CSS url() and @import, Markdown links and CSS selectors: language servers expose paths as document links, not definitions, and none resolves class/id to selectors.
- ide-lsp: textDocument/documentLink (lsp_document_links), resolving links that lack a target.
- Editor: when the server has no definition, follow its document links, then URLs and quoted / Markdown / url() paths in any language. Server file links are checked to exist; root-relative paths also resolve against resource roots. Cmd-hover underlines the whole link.
- ide-language: tree-sitter web references (class / id attributes, href="#id", var(--x)) and .class / #id / --var definitions from stylesheets and <style> elements, indexed as symbols. web_goto looks them up by exact name (ProjectIndex::symbols_named), using the open document's unsaved text.
- Detect public/ of package.json modules as a resource root (Vite, Next, CRA serve it at /).
