/* ==========================================================================
   Palissade — public site palissade.ca
   Layout modelled on the Soscar template (licence bought by Groupe Solutions TI, see README « Template »),
   written from scratch for the Palissade brand (brand kit: #1F58C7, #0F2745, #A4A9B4, #E6EBF2, Segoe UI/Arial).

   Rules: no inline style anywhere (CSP style-src 'self'), no script, no third-party resource.
   Every colour goes through the tokens of :root. Light and dark through prefers-color-scheme.
   Animations are CSS only and stop under prefers-reduced-motion.

   Cascade layers: tokens < base < layout < components < utilities. The licensed template stylesheet, when dropped
   in (Website:Theme:VendorStylesheet), is unlayered and loaded last, so it wins over every layer here.
