/* =============================================================================
   NEXUS_AI v2 — design system
   One stylesheet for the shell and the new pages (home, install, pricing, chat).
   Migrated page content (docs, cabinet, news, rankings) lives in content.css and
   uses the same tokens, so both themes and the new palette apply everywhere.
   No external fonts or CDNs: the site must load the same everywhere.
   ============================================================================= */

/* ---------- tokens ----------
   Palettes: ember (default: amber + teal in the dark theme, "linen" terracotta + sage in the light one), lime (signal green on cool greys), cobalt (blue + teal).
   Chosen with <html data-palette="…"> (assets/js/boot.js, ?palette=lime to preview). Each palette has a light
   and a dark variant tuned separately: a colour that reads well on white is too dull on black and vice versa.
   Everything else derives from --brand / --brand-ink / --brand-2, so a new palette is ~10 lines. */
