RDF to .q42 Comparator

Remote URI import uses jsDelivr (for this repo), the local Qualia daemon /proxy/fetch relay when running, or a public CORS fallback. Upload and fetch show live progress bars. Parsing runs in the browser (N-Triples / N-Quads in JS; unified .q42 via the 256-byte v3 header).

The page loads Schema.org 30.0 automatically — N-Triples source vs the published unified .q42 volume — then runs Compare. You can still drop your own files or fetch a URI. LZ4 SuperBlocks live inside .q42; there is no separate .c.q42.
