/* Biz Edge hosted shop. Framework-free and small on purpose: fast first paint on mobile data.
   Merchant colours arrive as --sf-primary / --sf-secondary (set inline by _ShopLayout, ShopColors).
   Text ON a colour uses --sf-on-*; a colour used AS text on white uses --sf-*-ink (darkened if too
   light to read), so any pick stays legible.
   Themes: body.theme-classic (default), body.theme-modern, body.theme-minimal. */
