/* Hefaistos Software – Portál v0.2.0
   Vzhľad v štýle aplikácie Hefai-soft Fasting: systémový iOS look – neutrálne sivé
   pozadie, biele karty s výrazným zaoblením, sýte systémové akcenty, jemné oddeľovače.
   Paleta prevzatá z ui/Theme.kt (AppColors) aplikácie Fasting.

   Denný / nočný režim:
   – bez voľby („auto“) rozhoduje nastavenie systému návštevníka,
   – prepínačom v hlavičke sa dá vynútiť <html data-theme="light"> alebo "dark".
   Farby pozadia, panelov, textu a akcentu sa naďalej dajú meniť v Administrácia → Vzhľad;
   nočná paleta ich pri tmavom režime prekrýva (akcent zostáva, len o odtieň svetlejší).

   Pôvodná tmavá „kováčska“ téma zostáva pre istotu v style-classic.css. */
