/*
    styles.css
    Clean, responsive CSS extracted and organized from the provided single-file HTML.
    How to customize:
    - Update CSS variables in :root to change theme colors and spacing.
    - Replace placeholder images in assets/img/ keeping the same filenames for zero-code swaps.
    - Section blocks mirror index.html structure. Look for EDIT comments in HTML.
