/*
 * Esquisse — shared site design system
 * ----------------------------------------------------------------------------
 * Single source of truth for the public marketing pages (index · welcome ·
 * vision). Palette + type tokens are harmonised with the investor deck
 * (style-deck.css): brick-red accent, warm paper, Crimson Text headlines.
 *
 * Page styling is scoped under `.site` (index/welcome) so nothing here leaks
 * into the other pages that share style.css (legal-notices, press-release).
 * `style-vision.css` consumes the same :root tokens.
 *
 * Loaded AFTER style.css, so `.site`-scoped rules win over the global defaults.
