   BERTHOUD BLUES BASH — EVENT PAGE STYLESHEET
   Deliberately separate from style.css: this page's brand (vintage
   American blues poster meets Colorado Front Range) is its own thing,
   not a Bayou Smokehouse sub-brand, so nothing here should leak into
   or depend on the main site's design system.
