/**
 * ============================================
 * BLOCK 03: RESULTS - Styles
 * File: blocks/03-results/results.css
 * Version: 5.0 - Aurora Premium Design
 * 
 * CHANGES v5.0:
 * - Removed all var(--tg-theme-*) hardcoded backgrounds
 * - Aurora glass header (results-header + params-bar = one glass card)
 * - Hotel cards with glass morphism
 * - Uses shared tokens from variables.css
 * - Integrates with .screen layout from base.css
 * - Transparent background (aurora visible)
 * 
 * DEPENDS ON:
 * - shared/variables.css  (tokens)
 * - shared/base.css       (.screen, .glass-card)
 * ============================================

/* ============================================
   RESULTS SCREEN
   
   .screen from base.css provides:
   - position: absolute; top/left/right/bottom: 0
   - padding-top: var(--content-top)
   - padding-left/right: var(--screen-padding-x)
   - padding-bottom: var(--content-bottom)
   - background: transparent (aurora visible)
   - display: flex; flex-direction: column (when .active)
   
   We only override overflow to prevent double-scroll.
   .hotels-list is the only scrollable area.
