   Layout concept: the preacher's study. The book sits on the sand-coloured
   desk of the posters, then the page reads like a sermon outline: one strong
   column, Roman-numeral divisions, and royal-blue bands taken from the cover
   for the two moments that matter, the method and the offer.

   One deliberate light look for every visitor: the colours of the book cover
   are the brand, so there is no dark variant. Every colour is set explicitly.
