/* ---------------------------------------------------------------------------
   Convertcy landing page.

   Hand-written, no framework. The palette is taken from the app itself
   (../RNconverter/app/constants/Colors.js) so the site and the product look
   like one thing:

     app fontColor / selectedItem  #462759  -> --brand
     app buttonColor / header      #9171A5  -> --brand-soft
     app focusedLine               #dbd0e1  -> --wash-2
     app focusedTextArea           #f7e8ff  -> --wash
     app buttonSuccessColor        #52B249  -> --accent (checkmarks only:
                                               it is too light for text)

   Contrast was checked against WCAG AA: body text 12:1, muted text 7.4:1,
   links 7.2:1. --brand-soft is 4.1:1, so it is only used for large text,
   icons and borders, never for body copy.
