 * Misson — Auth-näkymien CSS (login / logout / password reset).
 *
 * Yhden tarkoituksen tiedosto: ei riipu Bootstrapista, ei käyttäjäsessiosta.
 * Käyttää design-tokeneita (tokens.css), joten dark-mode toimii ilman
 * erillisiä overrideja. Inputit, painikkeet ja alerts on rakennettu tähän
 * suoraan, jotta vendor-CSS ei rikkoisi niitä.
