/* =====================================================================
   DTA-FJD — design system
   ---------------------------------------------------------------------
   Public shop pages (ShopLayout, scoped under .fjd-site) get a bespoke
   industrial/geospatial visual language: dark-slate neutrals, a single
   restrained "survey orange" accent, a technical display face paired
   with a readable body face, asymmetric editorial layout, generous
   whitespace. Admin/account pages keep the plain Bootstrap defaults
   below (unchanged) since they are out of scope for this phase.

   FONT NOTE: no network access is available in this environment to
   fetch/self-host a distinctive display webfont, and no local font
   files exist in the repo (only ImageSharp/QuestPDF's Lato ships as a
   NuGet-embedded PDF font, unrelated to the web front-end and not
   suitable for @font-face without extraction). Per the task's explicit
   fallback instruction, the display and body faces below both use a
   well-chosen SYSTEM font stack — "Segoe UI Variable"/Segoe UI leading
   on Windows, falling through to strong cross-platform equivalents —
   rather than a generic "Inter/Google Fonts everywhere" look. Revisit
   with a licensed self-hosted grotesque (e.g. a condensed technical
   face) once one can be added to wwwroot/fonts without a network call.
