/* PBMares brand (DEF-01): teal dominant, Dark Gray for supporting text and dividers, Accent Dark Blue for links
   and focus rings, Accent Orange once as a thin decorative rule, Light Tan only as a pale background. White text
   sits on teal (5.12:1) or dark blue (9.40:1) only: orange fails with white (2.80:1), so it never carries text.
   Fonts: Lato first, the font pbmares.com itself loads, so the widget matches the site; then the brand document's
   faces (Proxima Nova or Malgun Gothic for headings, Calibri for body) and common system fallbacks. The plugin loads
   no web fonts: the host page already loads Lato. */
