/* ============================================================
 * AUTH STRÁNKY S HORNÝM MENU A PÁTOU
 * ============================================================
 * Prihlasovacia a registračná stránka používajú rovnaké horné
 * navigačné menu a footer panel ako ostatné verejné stránky
 * (.header / .footer z assets/css/pages/public-pages.css).
 *
 * Tieto kontajnery mali pôvodne výšku celej obrazovky
 * (min-height: 100vh), pretože lišta ani päta neexistovali.
 * Teraz musia od výšky obrazovky odpočítať lištu, inak by
 * karta bola odsunutá o jej výšku a stránka by mala dve
 * „obrazovky“ scrollovania.
 *
 * --auth-header-height zodpovedá výške .nav min-height: 74px
 * z public-pages.css.
 *
 * Samotné tlačidlá v lište sa nemenia cez CSS:
 *   • login.html    – odkaz „Prihlásiť“ je vynechaný, ostáva
 *                     iba „Zaregistrovať“ (triedy btn btn--primary btn--sm)
 *   • register.html – odkaz „Zaregistrovať“ je vynechaný, zostávajúci
 *                     odkaz „Prihlásiť“ nesie rovnaké triedy
 *                     btn btn--primary btn--sm, takže má garantovane
 *                     rovnaký dizajn ako tlačidlo „Zaregistrovať“.
