/* buhr-consulting.com — "Selective colour" redesign.
   The page reads like a black-and-white photograph with one red element in it:
   photos, type and logos are monochrome, and red appears only where it means
   something — Maike's blazer, the full stops of the headline, and the button
   to book a call. Design rationale and prototype: the design review of
   2 October 2026.
   No inline styles anywhere: the production CSP allows style-src 'self' only. */
