/* resheniya.css - additions for the parametrized ResolutionPage template.
 * Loaded AFTER resheniya-fundament.css (which already imports site.css and
 * provides all .rf-* structural classes). Industry-solution pages reuse rf-*
 * for head, hero, sections, sorts cards, docs cards, FAQ accordion, big CTA
 * and add the few .rs-* deltas below for the things unique to the new pages:
 *
 *   .rs-badge          - "Решение" pill above the H1
 *   .rs-head__top      - flex row that holds the badge + "Updated:" date
 *   .rs-hero-preview   - 6-tile preview grid inside the hero left panel
 *   .rs-spec           - typical-kit spec table wrapper (uses .tbl class)
 *   .rs-info           - 3-col logistics info grid (like gp-info)
 *   .rs-case-big       - single big case card with photo placeholder
 *   .rs-related        - 4-col related links cluster
