   My Phonics Adventure — sales page
   Layout: the real worksheet pages are the hero material; sections alternate white and a cool tint,
   and the handwriting-line motif (solid · dashed · solid) from the workbooks marks the headline.
   Single light theme on purpose: it matches the printed pages.
