   Previously de-emphasized (opacity 0.55, 16px logo, plain <p>, no

   and confined outside its header nav -- action item 72
   (POOL_CHAMP_ACTION_ITEMS.md) flagged this as a mismatch against the
   real site and, per the user's direct instruction plus the actual
   shared brand.css Pixactly supplied, this is now corrected: that
   file's .nav-brand/.nav-logo rules (the real, current, shared-across
   -TTChamp-and-PoolChamp treatment) use FULL opacity, bold cyan text,
   and a 40px logo -- there is no "de-emphasized byline" pattern
   anywhere in Pixactly's actual design system. Values below now match
   .nav-brand/.nav-logo from that shared file directly. Markup changed
