/* Win-Win Technologies — company surface

   The company's own palette, from BRAND.md:

     oxblood    #5C1A17   the mark, headings, links
     parchment  #EFE3C6   the ground
     crest      #FFFFFF   the mark's snow line

   Oxblood was chosen over navy so the company mark cannot be mistaken for
   Recursivity's pale-blue-on-navy spiral at listing size. It is a deeper
   cousin of that app's light-theme accent #713331, so the two are related
   without repeating.

   Supporting tones are shared with /privacy, which wears the app's own
   parchment theme:

     ink    #2C2218   body text
     muted  #6A5F49   secondary text — a darker relative of the app's #A49164,
                      which at 2.5:1 on parchment was too faint to set text in

   Each product keeps its own colours inside its own page. Recursivity's dark
   page then reads as deliberate contrast rather than a clash. */
