/* Strata landing page. Tokens, fonts and hatch tiles live in base.css.
   Frame: a network-tooling product page built around one object, a drill core. A slim bar
   holds the logo and the download; the section links are a depth gauge fixed at the right
   edge. The first screen is a centre spine: headline, the sample domain, then the core as a
   column of six hatched layers. Each layer opens a record card beside it, left and right in
   turn, and under the last one sits the bedrock card with the one number. Below: the six
   layers as log cards, the shared-bedrock card with its drawing, four promises, questions on
   a depth rail, and a closing card with a core lying on its side. Flat colour only; malachite
   is the layer being drilled and the bedrock finding. */
