/* ===========================================================================
   Limen — Echelon Foundry visual system
   ---------------------------------------------------------------------------
   The palette, type scale, layout primitives, and component classes below are
   adapted from the authoritative Echelon Foundry site source
   (github.com/kemiller2002/consulting-company, assets/css/style.css) so that
   Limen is visibly part of the same family rather than an imitation of it.
   Echelon Foundry-owned material, reused within the organization.

   Everything after the "Limen additions" rule is new: code blocks, demo
   panels, the event trace, and the boundary table. Those follow the same
   conventions — borders over shadows, mono for metadata, generous space.

   Nothing in this file is known to the kernel or to any engine. The site's
   engines project *data* (`active: true`, `status: "Saving"`); CSS decides
   what that looks like. That separation is itself part of the architecture
   being demonstrated.
