   Design tokens are taken from the existing Bakhtawar Amin Hospital website
   (WordPress theme "Clinico", see docs/Repository-Analysis.md):

     brand red ......... #ff2323   (theme accent, hover #ff0000)
     heading ink ....... #373737   (.widget-title, .main-menu)
     body text ......... #7c7c7c   (body)
     hairline .......... #e3e3e3   (borders, tag cloud)
     surface ........... #ffffff
     canvas ............ #f5f7f9   (light neutral page background)
     typeface .......... Lato (body 14px / line-height 21px in the theme)

   Reusable behaviours copied from the theme:
     * section titles keep the theme's 3px left accent border ( .widget-title )
     * buttons keep the theme's uppercase 14px treatment ( .cws_button )
     * containers are 1170px wide and centred ( .container in layout.css )
