/**
 * Page Header Styles – Blueprint Theme v2.0.0
 *
 * All visual properties are driven by CSS Custom Properties set inline
 * by page-header.php via ACF field values (with global options fallback).
 *
 * Properties used:
 *   --header-height                (px)
 *   --header-padding-top           (px)
 *   --header-padding-bottom        (px)
 *   --header-title-size            (rem)
 *   --header-title-weight          (number)
 *   --header-title-transform       (none|uppercase|capitalize)
 *   --header-title-letter-spacing  (em)
 *   --header-subtitle-size         (rem)
 *   --page-header-text-color       (color)
 *   --header-content-max-width     (px) – only when set
 *   --header-image-blur            (px) – only when > 0
 *   --header-overlay-color         (rgba)
 *   --header-overlay-color-top     (rgba, slightly less opaque)
