/* ============================================================================
   DRAWBRIDGE front page.

   The world: an architect's sheet set for one gatehouse. Drafting vellum with
   a fine grid, green ink linework, gold only where the chain and the signed
   things are, slate for construction lines. Every section is a sheet with a
   number (A-101, A-201 ...) and the footer is the title block.

   Built on WayneUI 2.0.8 (assets/wayne-ui/, copied from its static path):
   tokens, Lato, container, buttons, tabs, tables, skip link and sr-only. All
   of WayneUI sits in @layer, so the unlayered rules here win quietly.

   Type: Big Shoulders Stencil Display (display), Architects Daughter (the
   hand-lettered annotations), Lato (body, from WayneUI). Both new faces are
   SIL OFL, self-hosted in assets/fonts/.

   File map:
     1. fonts and tokens       5. A-301 door schedule and explain
     2. paper, header, tags    6. A-401 assertion, A-501 notes
     3. A-101 hero drawing     7. A-601 build, A-701 site plan, A-801, footer
     4. A-201 passage          8. responsive, 9. motion (only with .motion)
