   Cal y Canto — construcción y arquitectura
   Plantilla de demostración · Studio ArtTec

   ONE stylesheet for all five pages. The other five templates inline their CSS
   because they are one document each; this one cannot. Five inline copies of
   ~30 KB is not mainly a weight problem, it is a DRIFT problem: the header,
   mobile menu, focus trap, ribbon and footer have to be identical across five
   files or the shared test baseline starts passing on page 1 and failing on
   page 4 for reasons invisible in a diff.

   Handing this template to a client means copying EVERYTHING in this folder
   except index.html, plus ../_shared/. Not just site.html — see CLAUDE.md.

   Lane: a set of construction drawings. Drawn grid, ruler gutter with tick
   marks, title block, and one site-marking orange used four ways only.
