/* Vega holding page — Direction C · Signal, hero only, no navigation.
   Logo and type updated 2026-10-13/14 to the new brand (see docs/brand/).
   Built from Figma node 31:210 ("01 · Hero · Temp").
   Colour, type and motion tokens come from tokens.css; nothing is re-declared here.
   The page itself is one static frame; the only JavaScript is the optional intro
   (intro-gate.js, intro.js — see the intro section below). */

/* Type pairing chosen 2026-10-14 against the new logo (design board P2):
   Outfit for the headline, Mulish for text, DM Mono for captions.
   Self-hosted latin subsets from Google Fonts, OFL licences alongside.
   The font tokens come from tokens.css (shared with /site since 2026-10-14);
   the faces are declared here so this page does not depend on main.css. */
