/* ==========================================================================
   TechForge ETD portals — shared stylesheet for both Razor portals
   (Pages/Portal/* tenant portal and Pages/Admin/* admin portal).

   Structured as design tokens + components. Every colour, radius, shadow and
   easing is a custom property declared once in :root, so a theme change is a
   token edit rather than a sweep through the rules. The dark palette is the
   same token names redefined under prefers-color-scheme, which is why no
   component rule below mentions a literal colour.

   Class names are the contract with the .cshtml pages and are deliberately
   unchanged from the original stylesheet — restyling happens here, not in
   markup. Two constraints from the CSP set by Middleware/SecurityHeadersMiddleware:
   `font-src 'self'` rules out webfonts from Google/CDNs (hence the system font
   stack), and `img-src 'self' data:` rules out remote imagery.
