 *
 * JÍDELNA — Public Login screen v2
 * Implementováno v rámci JIDELNA UKOL 002 (Fáze 1b: Kostra modulu).
 *
 * Vychází z designer dropu dokumentace/Zdroje nový UI/Jídelní systém/login-v3.css.
 * Designerova vlastní namespace (--bg-x, --fg-x, --accent, --st-x, --fs-x) je
 * 1:1 přemapována na PPP --ui-x design tokeny. Žádné nové role do designer
 * katalogu, žádné hardcoded barvy.
 *
 * Drobné odchylky proti designerovi (designer ustupuje, PPP zůstává autoritou):
 *   - login card radius:    12px → --ui-radius-large (8px)
 *   - brand-mark radius:    10px → --ui-radius-large (8px)
 *   - input/button radius:  5px  → --ui-radius-small (4px)
 *   - checkbox radius:      3px  → --ui-radius-small (4px)
 *   - badge pill radius:    11px → --ui-radius-pill  (999px)
 *
 * Pro UKOL 002 jen solo mode (jen login card, bez side panel). Side panel
 * s admin info a menu preview přijde ve Fázi 6 (JIDELNA admin).
 *
 * Soubor sdílí stylizaci pro public-login.ejs, menu-placeholder.ejs a
 * admin-placeholder.ejs — všechny tři používají stejnou jidelna-login-card-v2
 * strukturu.
