/* ============================================================================
   pages/auth.css — accesso, registrazione, recupero password
   ============================================================================

   Caricato da `layouts/auth.html`. Era `users/styles.html`, un blocco `<style>`
   dentro il template: 454 righe riscaricate a ogni visita della schermata di
   accesso, e mai messe in cache.

   L'`@import` che scaricava Inter e JetBrains Mono da fonts.googleapis.com è
   sparito. Due ragioni: i caratteri arrivano ora da `static/vendor` insieme a
   tutto il resto (PROMPT 27, parte 3), e questa pagina usava DUE caratteri che
   nessun'altra pagina del sito usa — era il sintomo più visibile delle due basi
   separate, due schermate dello stesso prodotto con due tipografie diverse.

   Le variabili `--vaitony-space-*` che questo file usa sono definite in
   tokens.css.
