/* =====================================================================
   Public home page (Views/Home/Index.cshtml) - emerald theme.
   Loaded ONLY by the home page (@section Styles); every rule is scoped to .home-shell (set by the page through
   ViewData["ShellClass"]), so the shared shell, the sign-in page and all signed-in pages are not affected.
   Built on the dmer-theme.css tokens (spacing, radius, type, touch size); only the emerald palette is added here.

   Contrast (WCAG 2.2 AA): white text is placed only on #065f46 (7.7:1) / #0f766e (5.5:1) or on the gradient with
   the dark scrim (>= 5.2:1 at its lightest point); #10b981 is used for fills and decoration, never behind text.
   Breakpoints follow the design system: mobile <= 767px | tablet 768-1023px | desktop >= 1024px.
