/* ScribeOps landing page.
   Direction "Datasheet": the page is the product's spec sheet — numbered
   sections, FIG. captions, hairline blueprint frames with registration marks.
   Tokens and the .blueprint / .btn / .card / .nav / .table components come from
   the Industry design system; the layout classes below replace the design
   canvas's inline styles so the page can be responsive and maintained.

   Light-only by design: the whole concept is ink on a technical ground, and a
   dark inversion would fight it. Every colour is stated explicitly so the
   viewer's theme never shows through. */
