/* ==========================================================================
   Greenlight Publishing — storefront
   AUTHORED BY HAND. build_site.py never writes this file.

   Two grounds, both taken from the product. The shop argues on INK, the warm
   brown-black of bookbinder's board. It reads on PAPER, the cream uncoated
   stock the paperbacks are actually printed on, and the free chapters are the
   only pages that use it — the switch means "you are now reading the book".

   The accent is not chosen. site_assets.py samples every jacket and writes
   three tones per title into site/data/covers.json; the builder sets them as
   --spine, --glow and --tint. 244 books supply the colour.

   Every pair named in site_audit.py CONTRAST is solved to 4.5:1 for text and
   3.0:1 for anything clickable. Do not nudge a token without re-running it.
