/* =========================================================
   Derbyshire Security - Modern Light Theme (Full File)
   Updates in this version:
   - HERO image remains perfect/full-width
   - HERO overlay box contrast improved (more readable)
   - Stronger text color + shadows for legibility
   - Header height stays fixed; logo overlaps without pushing layout
