🧷 CSS Custom Properties (Variables) Extractor
Paste any CSS and pull out every --variable-name: value; declaration — wherever it lives, not just :root — plus a lint check flagging var(--x) usages that reference a name that was never declared, and declarations that are never used.
This is a string/comment-aware brace scanner, not a full CSS parser — it tracks nesting (so a declaration inside a nested @media block is correctly attributed) but doesn't resolve @imports or evaluate calc().
