/* ==========================================================================
   SurfProtect

   Colours follow the visual identity proposal in
   `_resources/Obecné info/logo Surfprotect/surfprotect-loga-koncepty.docx`:

     blue       #1E6FA8  — Fortes, trust; the general UI accent
     dusty rose #D98BA3  — treated textiles / bed linen
     anthracite #37424C  — stainless steel; also the heading colour
     grey       #8E9AA3  — films

   The three colours appear together in the logo ring and in the thin rule
   under every section heading ("three materials under one protection").
