/* ---------------------------------------------------------------------------
   The Italian eInvoice Verifier, free on the site
   ---------------------------------------------------------------------------
   The product's verifier (Tools → Italian eInvoice Verifier) in the site's
   grammar: paper panels with a rule round them on the ruled sheet, flat grey
   for the drop zone, black pill buttons. Drawn by landing/src/einvoice.ts.

   Findings are notes, never red fills: an element with a rejection gets a red
   rule at its left edge, its name in red and a wash of a few percent; a
   warning the same in amber. The tree's values are in Geist Mono — they are
   the file's own characters, and a curly apostrophe has to look like one.
