/* IBE Reality — Login page (standalone, no Elastic dependency)
 *
 * Design principles:
 *   - Nielsen heuristics: error prevention, recognition over recall
 *   - Marcotte (2010) Responsive Web Design — fluid + breakpoint-driven
 *   - Apple HIG / Material — 44–48px tap targets
 *   - WCAG 2.1 AA — contrast >=4.5:1, visible focus, target size >=44x44px
 *   - Fitts's Law — primary action prominent and easy to hit
 *   - Krug — single clear action, minimal decisions
