   DIVI INLINE-CSS OVERRIDE
   Divi (parent theme) injects an inline `h1,h2,h3,h4,h5,h6 { color:#333 }`
   rule into every page. With higher specificity than a bare element, this
   single line forces every heading inside our `#top` scope to inherit the
   theme's text color by default. Light-themed sections re-darken via
   `#top .is-light h2…` blocks below — those have ID+class+element specificity
   so they correctly beat this rule.
