/* login.css — a porta de entrada da Banca Clinica.
   Nasceu do conserto da CSP fase 3 leva C (03/09/2026): o <style>
   inline do LOGIN_HTML morreu sob style-src-elem 'self' e a tela
   ficou nua. Redesenhada a pedido do medico, e afinada por ele em
   tres ordens: clara e calma; verde; e por fim "as cores como da
   Banca Clinica" — este arquivo veste a entrada com a identidade da
   propria Banca (estudio-tema): papel quente, linha areia, tinta
   #15181D, verde-verdigris #0B7A63, Instrument Serif + Onest.
   TUDO em CSS e SVG: /login e' tela pre-autenticacao e mantem a
   garantia de ZERO <script> (test_csp_eval e test_login_tela). */
