/* CaseOpp login-page skin. Structurally cloned from verishield_login.css
   (same selector list, same CSS custom-property names) but with CaseOpp's
   own real-site palette: navy #242732, teal #0097a0, white, Montserrat.
   Unlike the portal skin (caseopp.css), this page has no shared "colors
   below the header" to preserve — it's one self-contained login card — so
   the whole card is reskinned, not just a header slice. */
