/* MailMC - public/assets/auth.css (ukol M1.1.02.001, znovuotevreno zadavatelem).

   JEDNOTNY VZHLED PRIHLASENI VE VSECH SYSTEMECH ROMANA (public.labsmc.cz/admin,
   chatmc.cz/admin, mailmc.cz). Pravidla nize jsou PRENESENA ZNAK PO ZNAKU z
   originalu admin/admin_login.php na public.labsmc.cz - kopie originalu lezi v
   vystup/evidence/M1.1.02.001/REFERENCE-public.labsmc.cz-admin_login.php.txt.
   Nic se tu nevylepsuje ani neprejmenovava: nazvy trid, poradi vlastnosti,
   hodnoty i vsechny media queries (900 / 480 / 360 px, prefers-reduced-motion)
   jsou stejne jako v predloze. Kdo bude soubor menit, musi zmenu udelat i na
   ostatnich webech - jinak se print-screeny prestanou shodovat.

   ODLISNOSTI PROTI PREDLOZE - jen tam, kde original pouziva PHP:
     1. Predloha vklada styl inline do <style> a doplnuje tri hodnoty z DB
        (obrazek, ohnisko, kryci vrstva). MailMC nema inline styly (CSP
        default-src 'self', zadani/22), takze je tu externi soubor a hodnoty
        jsou zapsane napevno v podobe, kterou predloha pouziva jako vychozi:
        obrazek /assets/auth/admin.jpg, ohnisko 50% 50%, kryci vrstva 0.58.
     2. Predchozi verze souboru (M1.1.04.001) importovala tokeny adminu
        (/assets/admin/tokens.css). Import je pryc: predloha zadne tokeny nezna
        a shoda s ostatnimi weby ma prednost pred shodou s adminem MailMC.
        Tridy mmc-auth-* z predchozi verze uz zadna sablona nepouziva.
