   Fixes grey-on-blue and blue-on-blue readability site-wide.
   Targets every common dark-section pattern: heroes, final-CTA bands,
   page-hero blocks, subpage hero/CTA, .dark-section, and any section
   whose background uses --navy / --navy-mid / --blue.

   Order matters: this block sits at the end of shared.css so it
   overrides earlier rules that set grey or blue text on dark backgrounds.
   Page-local CSS files load AFTER shared.css and can still override
