/* ============================================================
   BEAKER & BATTER -- baking and confectionery, explained through
   real chemistry. Design: a bright "lab notebook meets bakery"
   world -- pale paper ground with a faint notebook-rule grid,
   two deliberate accents used structurally, not decoratively:
   amber/caramel marks the culinary side, teal marks the chemistry
   side, consistently, everywhere on the site.
