/*---*\
    Inner Page Masthead

    Title + breadcrumb hero strip for inner pages (not homepage).
    Green base with dark overlay; min-height and padding scale per breakpoint.

    KEY FEATURES:
    - ::before overlay (40% black) for text contrast over background photo.
    - padding uses var(--section-margins) offsets; 1200px+ adds header clearance.

    IMPLEMENTATION NOTES:
    - Deps: custom-properties.css, bootstrap .container-fluid.
    - Breadcrumb colour overrides only; markup/styles live in global.css.
    - Figma and field details: docs/specs/bedrockenvironmental-specs.md
