/* SLVP Software site styles. Shared by the home page and both product pages.
   Layout: one centered column (max 1080px), bands that run full width,
   each band's inner .wrap holds the side gutter.
   Look: payday envelope (sobre) and receipt slips; mango as the one bold accent,
   each product keeps its own color (BayadEra sea blue, Tigumi leaf green). */
