/* ==========================================================================
   Industry — design system tokens and component classes.
   Ported from the Claude Design project "Industry"
   (_ds/industry-eaf70cb2-2c71-45ce-b0bb-f2eb2a1c4d53/styles.css) plus its
   theme-dark.css variant. This file is the source of truth for the look;
   retune the tokens here and every page follows.

   Industry is a wireframe: steel-blue on a light technical ground, Barlow
   Condensed headings over Barlow, a modular grid, and cards/figures/buttons
   framed as blueprint objects — square-cornered, hairline-bordered, with "+"
   registration marks at the corners.

   Fonts are SELF-HOSTED (latin woff2 subsets), not pulled from Google Fonts.
   The upstream sheet opens with an @import from fonts.googleapis.com; that is
   deliberately dropped here. See the sprint-98 note at the top of ledger.css:
   loading webfonts off-origin pushed FCP 1.6s -> 4.0s on throttled mobile.
