/* AiB Platform — the Invoice Extractor's workspace grammar (rd- is its
   short prefix: the reader workspace on /free-tools/invoice-extractor/).
   Loaded by the widget partial itself (_invoice-extractor.html), after
   css/public/public.css and tools.css. The design is the owner-approved
   concept mockup (2026-08-16), spoken in the platform's tokens: paper and
   canvas, the document as a white sheet with a soft shadow, and the three
   semantic statuses doing the talking (--ok read verbatim, --warn derived or
   worth a look, --danger not an invoice). Sodium appears ONLY as the
   running indicator while a file is being read — the site's LIVE
   discipline. Marks are quiet by default (a tinted outline) and turn ink
   when pointed at, so the document stays a document.

   Ladder literals used: 1180 (the file rail folds into a strip above the
   viewer), 1019 (the record panel becomes the bottom sheet — the 1020
   two-column fold), 719 (phone). */
