   NEXIRA CONSULTING: BRAND, WEBSITE & DIGITAL SUPPORT (Stage 11-14B)
   Page-specific styles for brand-website-digital-support.html only. All
   selectors bd- prefixed. Reuses .sd-hero / .sd-crumbs / .sd-dots / .sd-faq
   (service-detail.css), .faq and .closing (nexira.css) read-only.
   Deliberately quieter than the flagship service pages: no service number,
   no hero image, complementary label. Stage 07E rule: no decorative short rules.
