/* ============================================================================
   COMPOSITE ANALYTICA | SHARED WEBSITE STYLES
   Refactored: 23 October 2026

   Loaded after bootstrap_system_2014.css (Bootstrap 3.1.0).
   This stylesheet is shared by the homepage, CheFEM, FEA consultancy,
   contact pages and the historical materials forum.

   Maintenance notes:
   - Preserve existing class names: several are used by archived forum pages.
   - The global margin reset is legacy behaviour and is intentionally retained.
   - Keyboard focus is blue; mouse/touch focus has no persistent dark outline.
   - Homepage navigation cards are scoped to .homepage-nav-cards.
