/* ============================================================
   Baldwin Digital — Engineering Ledger
   ------------------------------------------------------------
   The site's identity is editorial: cream stock, forest ink,
   Newsreader. This layer pushes that toward a *technical
   monograph* — the apparatus of engineering documentation laid
   over the same paper. Mono spec labels, hairline ruling with
   figure numbers, blueprint grids in the dark bands, and a
   build manifest.

   It exists so the site can read as a software studio without
   throwing away a design system that already works. Nothing in
   here changes a colour or a face that was already set; it adds
   a register.

   Loaded globally after components.css. Page CSS may override.
   ============================================================ */

/* ------------------------------------------------------------
   1. THE MONO REGISTER
   The spec label. Small, tracked, uppercase, forest. This is the
   single most load-bearing piece of the whole layer — it is what
   makes a paragraph of marketing copy read as documentation.

   3. BLUEPRINT GRID
   Drafting-paper texture. Only ever inside the forest-dark

   threshold of visibility: it should register as texture, not
   as a grid you can count.

   9. WORDMARK
   The subtitle under "Baldwin Digital" moves into the mono
   register. Smallest possible change, and it means the identity
   itself carries the engineering signal before you read a word
   of copy. Hidden on the narrowest screens rather than allowed
   to wrap under the brand name.
