/* ==========================================================================
   david-sanker.com — /enterprise-genesis/
   --------------------------------------------------------------------------
   The long-form page. Loaded in addition to main.css, which supplies the
   tokens, typography, footer and the .cta component.

   Two rules this page depends on:

   1. The system map is HTML and CSS, never an image. It has to stay
      selectable, translatable, searchable and legible at 390px, and a raster
      diagram is none of those things.
   2. Present and future are different colours, not different wording only.
      A blue eyebrow means it exists; a muted eyebrow plus a dashed rule means
      it does not. `data-status="future"` drives both. Never style a future
      layer the same as a shipped one.
