   Aligned to two real references:
   1) Agillic.com — deep navy (#1B263B), coral accent (#FA4554),
      light neutral background, Poppins for display type.
   2) The Hello $Firstname cover — bold navy type on an off-white
      page, tied together by a diagonal coral ribbon (literally
      the Bowtie of Personalization as a physical object).
   Ink/navy for the hero, nav and footer. Paper (off-white) for
   content sections, echoing the book's page. Coral as the single
   accent, reused from both references rather than invented.
