/* ==========================================================================
   B-Digital Mark blog -- base layer (loads on every blog page)
   Tokens, scoped reset, header, footer, buttons, shared hero furniture, CTA.

   Isolation rules for this whole directory:
   - Every selector starts with .bdmb / .bdmb-* (body and <html> carry them).
   - Tokens are declared on .bdmb, never :root, so nothing leaks to other pages.
   - Token values mirror the approved production homepage.
   - No !important, no bare element selectors outside the .bdmb scope.
