/* DTA Client Portal — full UX-1/UX-2 styling (Section 8 of SPEC.md).
   Hand-rolled CSS, no framework payload (UX-6.3) — mobile-first, WCAG-2.2-AA-conscious (UX-6.1).

   DESIGN TOKENS (UX-1.1): sampled from the live DTA marketing site build source —
   DTA-AerialDroneSurvey\src\AerialDroneSurvey.Web\Styles\tailwind.css (@theme block). That
   stylesheet documents the DTA identity as "engineering-drawing / map-sheet aesthetic built
   around the OFFICIAL brand green (#5CA745, sampled from the logo) and its black", with a
   hi-vis orange reserved for measurement callouts / alerts / focus. This file ports those exact
   hex values into portal-scoped custom properties (contour-600 #47842F is used as the DTA
   button/link primary — a shade darker than the raw logo green for AA contrast on white; the
   raw logo green #5CA745 is kept as --dta-contour-500 for accents/underlines/tints).

   Customer-layer tokens (UX-4.1) are emitted inline per request by MainLayout.razor/
   BareLayout.razor as CSS custom properties on `.portal-page`; the selectors below reference
   only the custom-property names, so this remains a single stylesheet for every page (admin,
   generic and customer-branded alike). admin.css (Area ADMIN only) imports/duplicates the same
   token block since there is no CSS build pipeline in this repo. */
